Archetypical [[TheFifties 1950s]] DomCom, slightly unusual in that it focused on the youngest member of the Cleaver family, 8-year-old (at the start) Theodore "Beaver" Cleaver. He had an older brother, the JuniorHigh-aged (also at the start) Wally. Parents Ward and June rounded out the family group. The series debuted on Creator/{{CBS}} in 1957, then after one season it [[ChannelHop channel hopped]] to Creator/{{ABC}}, where it ran until 1963. A reunion movie called ''Still the Beaver'' aired on CBS in 1983, which led to a subsequent series that aired on Creator/DisneyChannel (in its' infancy), Creator/{{TBS}} and syndication, evnetually being retitled as ''The New Leave it to Beaver''. TheFilmOfTheSeries was released in 1997 was somewhat of a present day look at the Cleaver clan, but with more of an AffectionateParody vibe.

Probably the third-most famous sitcom of TheFifties, behind ''Series/ILoveLucy'' and ''Series/TheHoneymooners''. Along with ''Series/FatherKnowsBest'', it is always invoked when looking back on 1950s culture and family life, whether as a matter of nostalgia, pop culture history, lighthearted parody, or scathing satire. People [[StealthPun always seem to dwell on]] the tract housing with white picket fences, or the fact that June Cleaver ''always'' wore pearls and high heels, even when doing the most menial tasks.

The Beaver was played by Jerry Mathers in the series, and by Cameron Finley in the film. Wally was played by Tony Dow in the series, and by Erik von Detten in the film. Ward was played by Hugh Beaumont in the series, and by Christopher [=McDonald=] in the film. June was played by Barbara Billingsley in the series, and by Janine Turner in the film.

The show is also notable for being [[TropeMaker one of the first to feature a clip-show finale.]]

!!This show provides examples of:
* AesopAmnesia: An archetypical example of a main child character (especially Beaver) forgetting his lesson by the next episode. This trait was spoofed in a [=TVLand=] promo for reruns of the series; the lesson would "enter one ear," float around without making contact with the brain, and "go out the other ear."
* TheAllAmericanBoy: Beaver.
** This is why Mathers got the job; they knew they had the right boy when, during his casting call, he expressed concern over missing his Boy Scout meeting.
* TheAllegedCar: During the last two seasons, Wally's other main friend [[ButtMonkey Lumpy]] drives one of these, and often mentions grabbing parts from a junkyard for it.
* AndStarring: "...Jerry Mathers as the Beaver."
* AnnoyingYoungerSibling: Beaver. Mainly in the Wally-centric episodes where the writers had nothing for Beaver to do except hang around and make obnoxious comments while everyone else was trying to have serious conversations.
* AscendedExtra: Penny was originally introduced as a little neighborhood girl who was being picked on by her older brother but she would eventually go on to replace Judy Hensler as Beaver's rival (a.k.a. the creepiest girl in class). Similarly, Gilbert appeared sporadically throughout the first few seasons but would end up replacing Larry was one of Beaver's best friends.
* BigBrotherIsWatching: In a sense, he was in the 1962 episode "Lumpy's Car Trouble," where Wally breaks the rules for borrowing Ward's car for a track meet, by allowing its driver (Lumpy) to take a "shortcut" on the way home. The car's exhaust system was damaged, forcing the boys to push the disabled car along the highway to a nearby garage. Wally and Beaver (along with Lumpy and Eddie) hope the damage won't be noticed, but Ward finds out anyhow: a co-worker of his had seen the boys push the car and (unwittingly) ratted them out. That evening at home, Ward takes his sons aside and tells him he's aware of what happened, and declares the car off limits "for awhile." The trope goes into effect when Wally asks his father who saw them; Ward refuses to reveal his source ... reasoning that -- because someone might be watching them -- the boys will always have to be on their best behavior.
* CatchPhrase:
** "Gee, Mom..." or "Gee, Dad..." or "Gee, Wally..."
** "Good evening, Mrs. Cleaver. My, that's a pretty dress."
** "Ward, old boy..."
* ChickMagnet: Wally is pretty laid back about girls, but they aren't laid back about him.
** Eddie Haskell claims to be irresistible to girls, although you [[UrbanLegendLoveLife never see any of them]].
* ChronicBackStabbingDisorder: Gilbert. In many episodes, he pressures Beaver into doing something that he knows is either wrong, dangerous or stupid, and sometimes would say that he would do it as well. Then, when Beaver caves and gets into trouble, Gilbert would make fun of him, and yet still claim to be his [[WithFriendsLikeThese 'best friend']]. If it were not for Beaver's innocence and kind nature, Gilbert would not have been so EasilyForgiven.
* ClipShow: The series finale. TropeMaker.
* ComicallyMissingThePoint: In one episode, Beaver decides at the last minute to cancel a babysitting appointment to have fun. When Ward has him call back, he learns that the mother found another babysitter and will not be hiring him to babysit again, after she had previously told him she won't consider another babysitter. Beaver is sad, Ward asks if he's learned a lesson, and Beaver says he has - don't babysit for somebody who won't keep her word.
* DadTheVeteran: In one episode Ward Cleaver mentions having been in the Navy Seabees as a surveyor during World War II.
* DeadpanSnarker: Both of the parents, but especially June.
-->'''Ward:''' A fine way to greet the returning breadwinner!
-->'''June:''' How much bread did you win?
* DescriptionCut: The final lines of the show's final episode.
--> '''June''': You know, spending an evening like this makes you realize how much Wally and The Beaver have grown up. \\
'''Ward''': Yeah. They're not little boys anymore. They're responsible individuals now, practically grown men. \\
'''June''': Mm-hmm. \\
(''cut to Wally and the Beaver sitting on the floor, playing with a wind-up toy clown, which June had found earlier'') \\
'''Wally''': (''excitedly'') Hey, Beav! Look at him go! Isn't it neat? \\
'''Beaver''': Yeah. Hey, Wally? Let ''me'' wind it up next time! \\
(''the boys exchange smiles'')
* DevilInPlainSight, DropInCharacter, MouthyKid: Eddie Haskell
* DidIMentionItsChristmas: At the very end of Season 1's "The Haircut", we see the Beav wearing an angel costume and singing "Hark the Herald Angels Sing" at a school pageant... after no prior mention of Christmas in the whole episode!
** Even odder, the episode -- which was as close as the series ever got to a ChristmasEpisode -- originally aired in ''October''.
* DispenseWithThePleasantries: From the 1997 movie.
-->'''Eddie Haskell Jr.''': You looked as though you just walked out the runway.
-->'''June Cleaver''': Eddie?
-->'''Eddie Haskell Jr.''': Yes, Mrs. Cleaver?
-->'''June Cleaver''': Cut the crap.
* TheEveryman: The Cleavers.
* EverytownAmerica: Mayfield
* EvilCounterpart: Eddie to Wally. Granted, he's more of just a {{jerkass}} counterpart.
* FatBestFriend: Larry Mondello, a type A, is Beaver's best friend for the first three seasons.
* {{Flanderization}}: Many who have seen and heard of this show tend to exaggerate its LighterAndSofter nature, forgetting that it dealt with such topics as divorce, alcoholism, and Beaver's Hispanic friend.[[note]]To give one an idea of how controversial the last was, in TheSixties, Creator/MadeleineLEngle's 1960 book ''Meet the Austins'' was actually censored to remove the protagonists' Hispanic friend.[[/note]]
* ForcedIntoTheirSundayBest: Happens to Beaver a couple times, to his great displeasure.
* ForgottenThemeTuneLyrics
* FromTheMouthsOfBabes
* GettingCrapPastTheRadar: More than you might think. In the first episode we have this exchange:
-->''(reading a note attached to flowers sent to Ward)''
-->'''June''': Who's Cornelia Rayburn? And when did she see you off your feet?
** In Season five's "Beaver's Electric Trains", Beaver tells Gilbert that Wally, who was a high school teenager at this point, takes a lot of "showers in the day time". It's safe to say that any hormonal teen who had to share their bedroom with a younger sibling could probably relate.
* GoldenMoment
* GoodParents: Ward and June are unambiguously good people, and good parents to Wally and Beaver.
* GrandFinale: "Family Scrapbook", which was [[TropeMaker the first]] proper series finale in primetime television history. It was also a ClipShow, and indicated future directions of the Cleavers' sons: Beaver has completed eighth grade (and thus is ready to enter high school), while Wally is graduating from high school and has been accepted to college.
* HappilyMarried: Ward and June.
* HatesBaths: Both Wally and the Beaver in the early seasons, when they are still preteens. In the very first episode, they fake taking a bath to avoid actually taking one.
* HaveAGayOldTime: The main character's nickname has led to a myriad of filthy jokes in later decades, such as the classic from ''Film/RevengeOfTheNerds'':
-->'''Guy 1''': What is the dirtiest thing ever said on television?
-->'''Guy 2''': I don't know. What ''is'' the dirtiest thing ever said on television?
-->'''Guy 1''': "Ward, I think you were a little hard on the Beaver last night."
* HerBoyfriendsJacket: This becomes a plot device in an episode in which Mary-Ellen Rogers wants to impress her friends, and charms Wally into letting her wear his letterman sweater.
* HiddenDepths: In one episode, June reveals that her aunt has raised her from childhood.
* HiddenHeartOfGold: Eddie occasionally shows that he's not such a bad guy, but don't tell anyone that.
* HighSchoolHustler: The obsequious-to-adults but JerkAss-to-younger-brothers Eddie Haskell.
* {{Housewife}}: June Cleaver is the classic/stereotypical embodiment of the '50s version of the trope.
** She got to wear slacks in a couple early episodes, but this was eventually nixed by the producers, who felt it too unladylike and/or too sexy for the character.
** In reference to the pearls and heels while doing housework, Barbara Billingsley later explained in interviews that she didn't always wear them, and when she did there were practical reasons for them. She had a hollow in her neck that showed up quite visibly on camera, which the pearls concealed. (Even in later appearances/interviews, she can be seen with either a high-collared blouse or a pearl necklace covering it.) Same with the heels; she sometimes wore flats, but as Dow and Mathers grew, she thought it would be best to maintain a bit of height over them.
* ImmuneToMindControl: Played with in one episode, where Eddie Haskell pretends to be hypnotised by the Beaver; true to form, the writers knew that no one can be hypnotised against their will.
* InstrumentalThemeTune: It's called "The Toy Parade", if you were wondering.
* IntergenerationalFriendship: Gus the firefighter
* JerkAss: Eddie Haskell
* KarmaHoudini: In one episode, Beaver gets suspended from riding the bus for a week, only to get his privileges back after writing an apology letter to the bus driver. Afterwards, Judy gets suspended from the bus and asks Beaver how he did it so that her parents wouldn't find out. Beaver tells her and she acts grateful, but, [[GenreSavvy as he suspected]], [[StatusQuoIsGod Judy soon went back to mistreating him]].
* KickTheDog: Eddie occasionally slips into this territory, such as the episode where he tries to ruin Beaver's friendship with a Hispanic boy just for laughs.
* KidCom: Possibly the UrExample.
* LaughTrack: At the time this series came to be, this was just the start of {{LaughTrack}}s becoming a common, standard practice in television comedies.
* LockedOutOfTheLoop: To preserve Beaver's innocence, his parents conceal the fact that their visiting friend is an alcoholic. Later, the guest tells Beaver that he has an illness that only liquor can treat, and Beaver dutifully gets him some alcoholic beverages. When his parents admonish him that that was the worst thing he could have done, he responds that they didn't tell him anything, and they realize that keeping him in the dark was not a good idea.
* MeanCharacterNiceActor: Ken Osmond (Eddie Haskell) was a complete straight arrow in real life, and later became a respected police officer.
* TheMovingExperience: Season 2's "Beaver Says Goodbye" has Beaver prematurely mention to his classmates that he's moving after overhearing Ward mention making an offer on a house in another town, only to find out the owner of that house accepted another offer; [[spoiler:resulting in the kids giving Beaver going away presents despite the fact that it turned out he wasn't moving after all]]. Interestingly, the Cleaver family would move to another house in Mayfield by the start of Season 3.
* NotAllowedToGrowUp: Generally averted, though Beaver aged more slowly than the actor portraying him did, especially later on. Still, in the series finale he is explicitly stated to be entering high school; Jerry Mathers was, at the time, a fairly reasonable 15 years old.
** Although it was stated that Beaver was starting a new grade every season, his maturity never seemed to progress. He was as childishly naive in the last season as he was in the first season and, with the exception of a couple of episodes, he never lost his disdain for girls despite the fact that he was clearly a teenager by the last season. The latter was particularly grating in light of the fact that Wally was practically drooling over them by contrast.
* ObliquelyObfuscatedOccupation: Ward, in spades. On occasion, we've seen Ward at the office - usually calling home, or receiving a call from June or Principal Rayburn - but his actual job is something of a mystery.
* ParentExMachina
* PetTheDog: Eddie gets a few chances to do this, such as when Beaver gets a stain on Wally's suit jacket and is unable to fix it before a school dance. Eddie sees the ruined jacket, laughs, but then notices Beaver's sad expression. Eddie ends up fast-talking Wally into wearing casual clothing to the event, which spares Beaver from getting found out and scolded.
* PickyEater
* {{Pilot}}: The show originally began as an episode of ''Studio 57'', an anthology series which initially aired on the short-lived Creator/DuMont Television Network in its first season, before moving to syndication in its second and final season. In the episode, Ward was played by Max Showalter (credited as Casey Adams) and Wally was played by Paul Sullivan.
* PleaseKeepYourHatOn: In the first season episode, "The Haircut", Beaver is hyped about playing in the school Christmas Pageant. Unfortunately, he loses his haircut money and has Wally act as amateur barber. Fortunately, Beaver gets to sing in the play. [[TakeAThirdOption He simply wears a winter tuque.]]
* PrecociousCrush: Beaver once developed a crush on a pretty new neighbor, however, both Wally and Eddie give him the business by saying if he's not careful, the woman's jealous husband will come after him. It doesn't help that at one point, the husband is shearing the hedges when he spots Beaver and tries to say hello to him... while the shears are still in his hands!
* PutOnABus: Larry Mondello.
* RemakeCameo: Barbara Billingsley, Ken Osmond and Frank Bank all make appearances in the 1997 film.
* ReportsOfMyDeathWereGreatlyExaggerated: A [[UrbanLegend popularly-spread rumor]] during the '70s and '80s was that Jerry Mathers had been killed in action during UsefulNotes/TheVietnamWar. This rumor persisted even ''after'' the now-adult Mathers appeared on ''Series/TheTonightShow'' with Johnny Carson to specifically refute the rumor by showing he was very much alive and was still an active actor. (Not only that, Mathers never served in Vietnam in the first place. He did try to enlist in the Marines, but they wouldn't take him, precisely for fear of the negative publicity should anything have happened to him. He wound up serving stateside in the Air National Guard instead.)
** Dow and Mathers also appeared briefly on an early episode of ''Series/SaturdayNightLive''. Mathers joked that he himself had started the rumor because he was afraid people were starting to forget about them. Dow responded, "Gee Beav, you big goof. I oughta slug ya!"
* {{Revival}}: A 1983 MadeForTVMovie and a 1985-89 "New" series focusing on the adult life of the Beaver.
* SecretDiary: Ward gives aspiring novelist Beaver a diary, telling him it's for private, personal things -- but also that great writers have used ideas they first recorded in childhood diaries. Beaver is subsequently late coming home from school, so of course the ''first'' thing his parents do is [[{{Hypocrite}} break into his diary]], where he's written lurid accounts of criminal activity. Despite the setup, it never occurs to them that these are anything but factual.
* SeriousBusiness: Frequently, and it's justified in that the show is written from a child's perspective; when you're a kid, a lot of insignificant-when-you're-older stuff really ''is'' Serious Business.
* StandardFiftiesFather: Ward Cleaver was the original TropeNamer, back when StandardFiftiesFather was called MisterCleaver.
** Even though Ward was truly a "father knows best" archetype, a couple of episodes did point out that he wasn't without his faults. One episode had Ward really come down hard on Wally and Beaver too hard, and when the boys ran into trouble, they were afraid to come to him for advice; Ward realizes that he acted out of haste. In another episode, when Wally and Beaver are late a couple of times delivering newspapers, the parents try to pick up the slack by delivering for them except they delivered the wrong papers not knowing that Wally and Beaver already had completed that day's delivery run with the correct ones, and they cause their sons to get fired.
* SuspiciouslySimilarSubstitute: Harry Henderson for Larry Mondello as the token fat kid.
** Penny for Judy Hensler.
* TeachersPet: Judy Hensler in Beaver's class borders on TheInformant.
-->"Mr. Willet, here's a list of everyone who talked while you weren't in the room."
* TheTeaser: First-season episodes had one narrated by Hugh Beaumont.
* UnwantedGiftPlot: One episode is about Beaver giving his mother a sweater that she ''really'' doesn't like, but she's too nice to tell him about it. And then he suggests that she should wear it to a parent/teacher meeting.
* VerySpecialEpisode: One about divorce and another about alcoholism.
* VillainWithGoodPublicity: Eddie tries this, but June and Ward can generally see through it.
* WomenDrivers: Referenced but not actually used when June learns to drive relatively late in life.
* YourTomcatIsPregnant
