Before Night Falls (Spanish: Antes que anochezca: autobiografía) is the 1992 autobiography of Cuban writer Reinaldo Arenas, describing his early life in Cuba, his time in prison, and his escape to the United States in the Mariel Boatlift of 1980. It received a favorable review from The New York Times and was on the newspaper's list of the ten best books of 1993. The book was adapted into a film of the same name in 2000, starring Javier Bardem and Johnny Depp.
On May 29, 2010 the premiere performance of Before Night Falls, an opera by Jorge Martín, took place at the Fort Worth Opera. The opera follows the book by Reinaldo Arenas closely.
