Kenneth Elton Kesey (September 17, 1935 November 10, 2001) was an American writer best known for penning the novel ''Literature/OneFlewOverTheCuckoosNest'' (which was adapted into the award-winning [[Film/OneFlewOverTheCuckoosNest film]] of the same name), as well as the less famous but equally lauded Pacific Northwestern epic, ''Sometimes a Great Notion'' (which was itself adapted into a film directed by and starring Creator/PaulNewman).

If that's all you know about Ken Kesey, though... you're in for [[Music/TheGratefulDead a long, strange trip]].

To some, Ken Kesey's crowning achievement is not the composition of two classic 20th century novels, but instead his leadership of the [[NewAgeRetroHippie Merry Pranksters]] and his role in the spread of [[TheSixties late-1960s]] psychedelia[[note]]Both the culture and the drugs.[[/note]]. Ideal places to find information on the adventures of Kesey and the Pranksters are ''The Electric Kool-Aid Acid Test'' by Tom Wolfe, and to a lesser extent ''Hell's Angels'' by Creator/HunterSThompson and the poem "First Party at Ken Kesey's with Hell's Angels" by Creator/AllenGinsberg.

He was caricatured in ''Film/AcrossTheUniverse'' as "Doctor Robert".

!!Works by Ken Kesey with their own pages:

* ''Literature/OneFlewOverTheCuckoosNest''

!!Other works by Ken Kesey contain examples of:

* TheAllConcealingI: ''Somtimes a Great Notion'' has a strange example. The entire novel is written in the first-person, but the narrator can vary, and there are no explicit indications that the narrator has shifted. There are, however, subtle clues, such as the new narrator mentioning the previous narrator in third person.
* {{Epigraph}}: ''Sometimes a Great Notion'' quotes the part of the folk song "Goodnight, Irene" that gives it its title:
-->''Sometimes I live in the country\\
Sometimes I live in town\\
Sometimes I have a great notion\\
To jump in the river and drown''
* FlippingTheBird: In ''Sometimes a Great Notion'', the protagonist displays his late father's amputated arm from a pole atop his house, with all the fingers save the middle one tied down, as a gesture of defiance against the union loggers with whom he's feuding.
* LaundromatLiaisons: In ''Sometimes a Great Notion'', a forbidden tryst in a laundromat is one of the only extraordinary acts of the normally mild-mannered and henpecked Real Estate Hotwire.
* UsefulNotes/TheOtherRainforest: ''Sometimes a Great Notion'' is a "burly," "brawling" novel about a family of loggers in Kesey's home state of Oregon. Regarded as the "''Literature/MobyDick'' of the Pacific Northwest," it is SomethingCompletelyDifferent from ''One Flew Over the Cuckoo's Nest''.
* TitledAfterTheSong: ''Sometimes a Great Notion'' takes its title from the song "Goodnight, Irene", popularised by Music/LeadBelly.
