The Little Hours is a 2017 black comedy film written and directed by Jeff Baena and loosely based on stories from the third day of The Decameron, a 14th-century collection of novellas by Giovanni Boccaccio. It stars an ensemble cast featuring Alison Brie, Dave Franco, Aubrey Plaza, Kate Micucci, John C. Reilly, Molly Shannon, and Fred Armisen.

Set in the 14th century, The Little Hours uses modern dialogue – in the spirit of its source material – improvised by the actors based on Baena's detailed outline. It focuses on the sex lives of its characters, including nuns at a convent (Brie, Micucci, Plaza and Shannon) in rural Tuscany, a local coven of witches, and a young servant (Franco) who ends up pretending to be a deaf-mute gardener at the convent after running away from his master (Nick Offerman).

It premiered at the Sundance Film Festival on January 19, 2017, and was theatrically released by Gunpowder & Sky, the company's first such distribution, on June 30, 2017. Muted complaints from Catholic groups did not affect the film, which received generally positive reviews from critics featuring praise for the cast's performances.
