Elmer Gantry (1927) is a satirical indictment of fundamentalist and evangelistic religion that caused a great scandal when it was first published. It was written by Nobel Prize winning American author and playwright Henry Sinclair Lewis.

Regarded as a landmark in American literature, 'Elmer Gantry' is a piercing portrait of a smooth-talking evangelist who rises to power within his church. But Elmer Gantry is a hypocrite and a philanderer, and his self-indulgent ways threaten to destroy everything.

The book was adapted into a 1960 film starring Burt Lancaster and Jean Simmons.
