Major Garland Briggs
- Cool Old Guy: More like "Cool Middle-aged Guy", but close enough.
- Incorruptible Pure Pureness: What more can you say about a man whose greatest fear is the "possibility that love is not enough"?
- Spock Speak: One of the causes of the distance between himself and his son is just how bizarrely-eloquent he is.
Robert "Bobby" Briggs
- All Girls Want Bad Boys: Laura Palmer's last relationship is with him. Subverted in that she humiliated him by destroying his "bad boy" posturing, as next to her he was both weak and innocent.
- Get Rich Quick Scheme: Spends most of his time coming up with these, and he's terrible at it.
- Jerk with a Heart of Gold: He mellows out over the course of the show.
- Large Ham: Bobby can be quite hammy when he gets emotional. Some of the best examples can be seen in the pilot episode when he's both accused and later questioned about possibly murdering Laura Palmer as well as in the fourth episode with his big AAAAAAMEEEEN!!! at Laura's funeral, and earlier in the same episode when his father implies that he's afraid of said funeral (specifically the last part of his response to that).
- Mr. Fanservice: He's very, very pretty.
- Rebellious Spirit: Very different from his wholesome parents.
- Smoking Is Cool: And as expected, his far more clean-cut father doesn't approve of it.
Played by: Mary Jo Deschanel
William "Doc" Hayward
Played by: Warren Frost
- Not So Stoic: While he's generally a calm and reasonable man, he still has his limits, as demonstrated by his altercation with Albert early on, where he gets infuriated that Albert insists on keeping Laura's body for the upcoming funeral to perform an autopsy.
- Beauty Mark: Next to her left eye.
- Betty and Veronica: The Veronica to Annie's Betty. In a twist, she's actually sort of a better person than Donna.
- Cloudcuckoolander: Mostly in the early episodes.
- Daddy's Little Villain: Inverted - A majority of the time, her shenanigans are done to spite Ben, directly or indirectly. For a laugh in the earlier episodes, anyway.
- Generation Xerox: Becomes every bit as conniving as her father as the series goes on.
- Smoking Is Cool: Although she seems to quit around the middle of the second season.
Benjamin "Ben" Horne
Played by: Richard Beymer
- Large Ham: Especially in the middle-to-later episodes when things start to fall apart for him, which causes him to get much more dramatic and uncomposed, but especially so in the episodes after he has a complete breakdown and starts acting and dressing like General Robert E. Lee. Even before that though, he fits the subtler variety of ham pretty well. His speech patterns can best be compared to that of Lionel Luthor from Smallville, in that both of them put emphasis on any words and parts of their lines that they feel are important.
- Sharp-Dressed Man: In contrast to the retro-'50s style that most of the town dresses in, Ben favours '80s patterned ties and double-breasted suits.
- Villainous Breakdown: Several episodes in the making, but he finally goes well and truly off the rails when he loses One-Eyed Jack's.
- What Have I Become?: He asks himself this a few times, only to shrug it off again.
Ben Horne's sleazy brother. He actually doesn't have too big of a role in the show, but he occasionally helps Ben with his schemes.
- Big Eater: He fell in love Brie-on-baguette sandwiches when he went to Paris on a business trip for Ben. He brings home no less than four of them and insists that Ben try one. As a rule, he winds up developing a taste for at least one exotic or unusual dish from every foreign country he's been to, and likes to tell people about them in great detail.
"Big" Ed Hurley
Played by: Everett McGill
- Will They or Won't They?: Throughout many episodes, it's very clear that he and Norma still have strong feelings for one another, but due to ending up with different people, they are constantly conflicted about whether acting on their feelings is the right thing to do. Later in the second season, they start getting much closer again when they drift further apart from Hank and Nadine respectively because of newer developments such as Hank going back to jail and Nadine falling in love with Mike Nelson.
Played by: James Marshall
Biker teen who lives with Ed and Nadine instead of his parents, who, he tells people, died in a car accident.
- The Ditz: Almost astonishingly stupid. As Laura Palmer says in one of her tapes, "James is sweet, but he's so dumb."
Played by: Wendy Robie
- Big Damn Heroes: She saves Ed when Hank tries to kill him.
- Cloudcuckoolander: Doesn't even begin to describe her!
- Driven to Suicide: At the end of season 1, she tries to overdose on pills out of depression when she can't sell any of of her cotton balls since not many people are interested in silent drape-runners, which she had just created with them, hoping they would make her and Ed rich. Thankfully though, it only sends her into a coma, which she awakens from a few episodes later.
- Genki Girl: Post-coma in season 2, when she thinks that she's a teenager.
- Woman Child A justified example. For some strange reason, she awakens from her coma near the beginning of season 2 thinking she's still a teenager in high school, and therefore, has the mindset of and acts like one.
Dr. Lawrence Jacoby
Played by: Russ Tamblyn
- Cloudcuckoolander: Dr. Jacoby was born in Hawaii and has had an obsession with the place all his life, dressing in tropical shirts and decorating his entire home with Polynesian kitsch.
- Cool Shades: He almost always wears a pair of 3D glasses.
Played by: Chris Mulkey
- Childhood Sweetheart: To Ed.
- Cool Big Sis: She acts as one towards Shelly Johnson, and is a literal one to Annie Blackburn.
- Fanservice with a Smile: She is played by Peggy Lipton after all.
- Greasy Spoon: Runs her own diner.
- Will They or Won't They?: Throughout many episodes, it's very clear that she and Ed still have strong feelings for one another, but due to ending up with different people, they are constantly conflicted about whether acting on their feelings is the right thing to do. Later in the second season, they start getting much closer again when they drift further apart from Hank and Nadine respectively because of newer developments such as Hank going back to jail and Nadine falling in love with Mike Nelson.
Played by: Eric Da Re
- The Aggressive Drug Dealer: Well ... sort of. He is aggressive and does sell drugs to high school kids, but they seek him out to buy them.
- Although, at the point of the sales, he doesn't do things by halves, and will straight-up threaten to kill his customers unless they fulfil their end of the deal.
- Ax-Crazy: He takes this trope to a literal degree when he awakens from his coma in the middle of season 2 and the first thing he tries to do is murder Shelly with an ax.
- Crazy Jealous Guy: When he finds out that Shelly has been having an affair with Bobby, he tries to murder both of them even though he generally treats Shelly horribly and doesn't really give her a reason to love him to begin with.
- Butt Monkey: In the second season.
- Convenient Coma: Well, he does clearly have some brain damage, but it's only convenient for some, who would have preferred him dead.
- Red Herring: Despite his sadism, violence, frequent cold-blooded killing and being present at the scene of her murder, Leo did not kill Laura Palmer.
- Redemption Equals Death: Releases Major Briggs from captivity so he can warn Shelly. Windom Earle leaves him in a situation he's highly unlikely to have survived.
- Villain Decay: Leo has the bad luck of being the absolute middle man. Terrifying to the teenagers who are dabbling, easily manipulated by the real powers in Twin Peaks.
Played by: Mädchen Amick
- Author Appeal : She kisses Gordon Cole, played by David Lynch himself. Cue Crowning Momentof Funny when her boyfriend, Bobby, comes in.
Gordon Cole : You are witnessing a front three-quarter view of two adults sharing a tender moment. [to Shelly] Acts like he's never seen a kiss before.
Dale Cooper : Uh, Gordon…
Gordon Cole : [to Bobby] Take another look, sonny! It's gonna happen again.
- Domestic Abuse : Her husband forces her to do all the chores, beats her with a soap in a sock at one point, and is deeply jealous.
- Ms. Fanservice: Not as much as Audrey, but she has her moments. And being played by Mädchen Amick doesn't hurt.
Margaret "The Log Lady" Lanterman
Played by: Catherine E. Coulson
Probably the most unusual of the Twin Peaks townsfolk, (which is saying a lot
). Margaret Lanterman, a/k/a "The Log Lady", is an eccentric
recluse who lives in a cabin in the forest. She is always seen carrying a log
(hence her nickname), which is implied to either contain the spirit of her dead lumberjack husband or, as of Fire Walk With Me
, to serve as a link to him in the Black Lodge — though she never voices either theory outright and is implied to be forbidden from doing so. Because of this, the other townsfolk think she's crazy.
She was with Laura five days before her murder. Also, her husband is Jurgen Prochnow.
Played by: Piper Laurie
- Bad Boss: Fires a guy in the pilot because he happened to be standing there when she was really pissed off.
- Corrupt Corporate Executive: She gives Ben Horne a serious run for his money.
- Latex Perfection: After faking her death, she disguises herself as a Japanese businessman named Mr. Tojamura in order to trick Ben.
Played by: Jack Nance
Mayor Dwayne Milford
Played by: John Boylan
Lana Budding Milford
Played by: Robyn Lively
- Heroes Want Redheads: Considering how Coop, Truman, Andy, and Hawk react when around her...
- Gold Digger: Pretty clearly.
- Informed Attractiveness: Whether you find her attractive or not, it's very difficult to say in all honesty that she's as attractive as every male in Twin Peaks finds her.
- Settle for Sibling: After her husband Dougie dies, she remarries to Dwayne, his brother. That's kinda gross.
Played by: Gary Hershberger
Played by: Dan O'Herlihy
- Dragon Lady: Possibly subverted in that she doesn't have nearly the self-assuredness one would expect from the trope. Her chief motivation is simply survival as she is manipulated and bullied by almost everyone in her life (except Pete and Sheriff Truman).
Played by: Sheryl Lee
- Go-Getter Girl: Laura subverts this as we get a glimpse of the darkness behind her seemingly perfect facade.
- Heroic BSOD: She suffers a major one in the prequel film when she finds out (or at least strongly suspects at the time) that BOB is possessing her dad, Leland.
The father of Laura Palmer, Leland is a well-respected lawyer in Twin Peaks. When he was a child, he met the evil spirit BOB and was possessed by him
. After hearing the news of his daughter's murder, Leland suffers a nervous breakdown, which results in him killing murder suspect Jacques Renault
at the end of season one.
At the beginning of season two, Leland awakens to find his hair has turned white. He becomes very upbeat, joyfully dancing and singing show tunes. However, it isn't long until he is arrested by Cooper and Truman for Jacques Renault's murder, but is soon released due to being well-respected by the townsfolk.Not long after the trial, he brutally murders his niece Maddie Ferguson (who bears a strong resemblance to Laura) the day before she is supposed return to her hometown, Missoula. The police find out about the murder and, with help from the Giant, Cooper reveals that Leland is Laura's killer. When Leland is taken in for interrogation, BOB assumes full control over his body and forces him to commit suicide just before leaving. Leland tells of his tragic childhood and the murders he committed and, with Cooper's help, dies peacefully while seeing a vision of his daughter.
- Abusive Parents: He definitely isn't one himself, but he becomes one whenever BOB is in control of him, including forcing him to commit Parental Incest.
- The Pollyanna: He becomes a weird, grown-up male version of this trope at the beginning of the second season after he's killed Jacques Renault and BOB has taken more complete control of him, which literally prevents him from staying upset about anything, including tragic events, for too long and to frequently break into singing and dancing.
Played by: Grace Zabriskie
Played by: Lenny Von Dohlen
Harold Smith is an orchid grower a close friend of Laura Palmer, who she met through working for the Meals-on-Wheels program. Harold never leaves his home
as a result of having agoraphobia (a fear of open spaces). Near the start of the second season, Donna Hayward befriends him in an attempt to get answers and discovers that Laura gave him her diary before her murder. When Harold finds out that Donna is trying to steal the diary, he goes insane and soon hangs himself, leaving a suicide note which reads ""J'ai une âme solitaire." (French for "I am a lonely soul."). Cooper and the Twin Peaks police use the diary to help find the identity of Laura's killer.
- Freak Out: Gets hit HARD with this when he finds out Donna's been tricking him to get Laura's diary.
- Hikikomori: Due to having agoraphobia.
- Nice Guy: At least until he completely snaps when he finds out about Donna's betrayal.
