The Battle of San Pietro is a documentary film directed by John Huston about the Battle of San Pietro Infine, 60 mi (97 km) from Naples, during World War II. It was shot by Jules Buck. It was released in the US in 1945 but shown to US troops earlier.

Huston and his crew—which included the British novelist and screenwriter Eric Ambler—were attached to the U.S. Army’s 143rd Regiment of the 36th Division. Unlike with many other military documentaries, it was claimed Huston’s cameramen filmed alongside the infantrymen as they fought their way up the hills to reach San Pietro. However, Huston's claim that the film was made during the battle was proven false by the research of Peter Maslowski in his 1993 book, Armed With Cameras.
