A live action television series aired between 1959 and 1963 based on the exploits of (RealLife) [[TheRoaringTwenties 1920s]] Chicago Prohibiton agent Eliot Ness and his group of loyal agents, nicknamed "The Untouchables" because of their refusal to be bribed or intimidated by the Mob as many others were at the time. Most notable for pursuing bootleggers and gangster UsefulNotes/AlCapone (and eventually arresting him--[[JusticeByOtherLegalMeans on tax evasion charges]]!) Later adapted as [[Film/TheUntouchables a movie in 1987]]. The film itself inspired a second television series in 1993, with Tom Amandes.

!!The original TV show contains examples of:

* AllForNothing: The two-part "The Unhired Assassin" ends with the man Ness was protecting being murdered anyway, only minutes after stopping ''another assassin'' from killing him. What rubs it in more is that he wasn't the intended target, because the second shooter was aiming for Roosevelt and missed.
* AnachronicOrder: Each episode jumps around back and forth between the years 1929 through 1934, as explained by {{Narrator}} Walter Winchell. The best example is DragonInChief Frank Nitti who appeared in 28 episodes through all 4 seasons despite being KilledOffForReal near the end of the first season in an episode set in 1934. In all his remaining episodes, the date is set before his death.
* BigBad: Capone, even after he is incarcerated, remains the puppet master.
* BondOneLiner: Delivered in typical hardboiled fashion, Ness uses these with enough subtlety to avoid {{narm}}.
* ByTheBookCop: No {{antihero}}es here.
* {{Chiaroscuro}}
* UsefulNotes/{{Chicago}}: The Windy City at its windiest.
* CleanUpTheTown
* CopShow
* DiscOneFinalBoss: Al Capone in the two-part pilot "The Scarface Mob".
* DragonInChief: Nitti, who runs TheSyndicate in Capone's absence and appears in way more episodes than his boss. (28 total, while Capone is only in 2 two-part episodes.)
* {{Dramatization}}: Several episodes would, in their credits, run the (dis)claimer: Tonight's Episode was based on the book by Elliot Ness & Oscar Fraley, although some events were fictionalized.
* TheFamilyThatSlaysTogether: "Ma Barker and Her Boys" pits Federal Agent Eliot Ness against the Barker clan, and depicts Ness as leading the assault on Ma Barker and her sons at their Florida hide-out. In this version, Lloyd, Fred and Doc are all present at the final shootout.
* TheFettered: Ness.
* FilmNoir: Or television noir, more accurately.
* FramingDevice: Winchell's narration often gives the impression of watching a visual interpretation of a printed newspaper article.
* TheGreatDepression
* JustAStupidAccent: Capone speaks in a heavy Italian accent, despite the fact that the real Capone was born in Brooklyn and spent his entire life in the United States.
* IncorruptiblePurePureness: Naturally. Played totally without irony in the series. Doesn't stop the criminals from making routine offers, though.
* MadeOfExplodium: If there is a car crash, it's going to explode. No exceptions, no matter how minor the accident is.
* MurderIsTheBestSolution: The Tri-State Gang kills everyone they hijack to keep anyone from identifying them. What's cruel is that they trick the drivers into thinking they'll let them live by covering their faces with a hood and chaining them to a tree, only to shoot them dead before they leave. What eventually leads to their downfall is that, in one case, they were too quick to leave the scene to check whether the driver was actually dead so he was able to give the license plate of the gang's truck later.
* {{Narrator}}: Each episode is narrated by gossip columnist Walter Winchell.
* NoSenseOfHumor: "Don't you ever smile, Mr. Ness?"
* PoliceProcedural: Somewhere between this and CopShow.
* PrettyInMink: One episode involves a stolen sable coat.
* RealityEnsues: In "The Unhired Assassin", the husband and owner of a dry cleaning shop gives a NoHoldsBarredBeatdown to the hoodlum responsible for collecting protection money in that area (at that time he was just bothering his wife, though). Said hoodlum doesn't go away but just comes back a few days later and murders him, and by using a kid to do so at that. The only saving grace is that he's immediately caught and will more than likely be sentenced to death in one way or another, whether by prison or Nitti.
* RewardedAsATraitorDeserves: Mobsters who betray or sell out who they work for tend to be paid off in this way by their new employers, because if they turned so easily against their former bosses then it's likely they'd eventually do so with them as soon as a better offer came along.
* TheRoaringTwenties
* [[TheFilmOfTheBook The Show of the Book]]: Based on Ness's semi-fictional memoir.
* SoOnceAgainTheDayIsSaved: the basic gist of Winchell's voiceover, although done rather cleverly.
* StarterVillain: The Pilot Movie was about Al Capone's arrest.
* StockholmSyndrome: An interesting reverse case in "Arsenal". A mobster comes to feel for his captives after they treat him as more than an animal, going so far later on as to try and save them when he's ordered by Nitti to execute them. [[RedemptionEqualsDeath He very quickly dies in the attempt, at the hand of the Untouchables no less.]]
* VeryLooselyBasedOnATrueStory: Most of the episodes do involve RealLife criminals and crimes of the period...the overwhelming majority of which Ness had nothing to do with.
* VigilanteExecution: Averted, because the plots of many episodes would be resolved in a matter of minutes if anyone had the nerve to just wipe out whatever set of gangsters is causing problems. It's generally always Ness and Co. that take them down, but not before they've caused a lot of damage.
* {{Workaholic}}: Implied. Although we see the criminal of the week's personal lives, the show never follows the Untouchables home. Judging by the late-night hours Ness pulls, he certainly is one (not to mention the [[MarriedToTheJob real Ness]]).
* YouHaveOutlivedYourUsefulness: Done by several gangsters against each other (usually to not have to share), but most often ordered by Nitti. Unsurprisingly, Nitti himself falls victim to this in "The Frank Nitti Story".
* YouLookFamiliar: typically of the era.

!!The 1990s TV show contains examples of:

* GunsAkimbo: Subverted when the senior member confronts a villain who framed him. The villain tries to resist with twin tommy guns. However, the idiot doesn't realize that given how heavy the gun type is, he can't even keep them level and so doesn't do much more than shoot up the floor in front of him with a lot of noise. For his part, the Untouchable simply shoots the villain with two carefully aimed pistol shots.
* MeekTownsman: An episode in which the Untouchables and some of Capone's men go to Kansas, and the mayor is the MeekTownsman. He makes a speech, talking as if he's saying something noble, but he's telling his townspeople [[BystanderSyndrome not to help Eliot Ness and co.]] fight the gangsters: "live to farm another day. To father, another day."
