Ian Frazier (born in 1951 in Cleveland, Ohio) is an American writer and humorist. He wrote the 1989 non-fiction history Great Plains, 2010's non-fiction travelogue Travels in Siberia, and works as a writer and humorist for The New Yorker.
Frazier grew up in Hudson, Ohio. His father, David Frazier, was a chemist who worked for Sohio; his mother, Peggy, was a teacher and an amateur actor and director who performed in and directed plays in local Ohio theaters. He graduated from Western Reserve Academy in 1969 and Harvard University in 1973.
The New York Times critic James Gorman described Frazier's 1996 humor collection Coyote v. Acme (in the title piece, Wile E. Coyote is suing Acme Corporation, the manufacturer of products such as explosives and rocket-propelled devices purchased by the coyote to aid in hunting the Road Runner; these products always backfire disastrously) as the occasion for "irrepressible laughter in the reader." Gorman rates Frazier's first collection, 1986's Dating Your Mom, as "one of the best collections of humor ever published.
