Jonathan Samuel Carroll (born January 26, 1949) is an American fiction writer primarily known for novels that may be labeled magic realism, slipstream, or contemporary fantasy. He has lived in Austria since 1974.

Carroll's debut book, The Land of Laughs (1980), tells the story of a children’s author whose imagination has left the printed page and begun to influence reality. The book introduced several hallmarks of Carroll’s writing, including talking animals and worlds that straddle the thin line between reality and the surreal, a technique that has seen him compared to South American magical realists.

Outside the Dog Museum (1991) was named the best novel of the year by the British Fantasy Society and has proven to be one of Carroll’s most popular works. Since then, he has written the Crane’s View trilogy, Glass Soup (2005), and, most recently, The Ghost in Love.
