Kenneth Elton Kesey (; September 17, 1935 - November 10, 2001) as Ken Kesey was an American novelist, essayist, and countercultural figure. He considered himself a link between the Beat Generation of the 1950s and the hippies of the 1960s.

When the publication of his second novel, Sometimes a Great Notion in 1964, required his presence in New York, Kesey, Neal Cassady, and others in a group of friends they called the Merry Pranksters took a cross-country trip in a school bus nicknamed Further. This trip, described in The Electric Kool-Aid Acid Test (and later in Kesey's unproduced screenplay, The Further Inquiry) was the group's attempt to create art out of everyday life, and to experience roadway America while high on LSD. In an interview after arriving in New York, Kesey is quoted as saying, "The sense of communication in this country has damn near atrophied. But we found as we went along it got easier to make contact with people. If people could just understand it is possible to be different without being a threat." A huge amount of footage was filmed on 16mm cameras during the trip which remained largely unseen until the release of Alex Gibney's Magic Trip in 2011.  After the bus trip, the Pranksters threw parties they called Acid Tests around the San Francisco Bay Area from 1965 to 1966. Many of the Pranksters lived at Kesey's residence in La Honda. In New York, Cassady introduced Kesey to Jack Kerouac and Allen Ginsberg, who then turned them on to Timothy Leary. Sometimes a Great Notion inspired a 1970 film starring and directed by Paul Newman; it was nominated for two Academy Awards, and in 1972 was the first film shown by the new television network HBO, in Wilkes-Barre, Pennsylvania.  Kesey was arrested in La Honda, California, for possession of marijuana in 1965. In an attempt to mislead police, he faked suicide by having friends leave his truck on a cliffside road near Eureka, along with an elaborate suicide note, written by the Pranksters. Kesey fled to Mexico in the back of a friend's car. He returned to the United States eight months later. On January 17, 1966, Kesey was sentenced to six months to be served at the San Mateo County jail in Redwood City, California. Two nights later, he was arrested again, this time with Carolyn Adams, while smoking marijuana on the rooftop of Stewart Brand's Telegraph Hill home in San Francisco. On his release, he moved back to the family farm in Pleasant Hill, Oregon, in the Willamette Valley, where he spent the rest of his life. He wrote many articles, books (mostly collections of his articles), and short stories during that time.
