Flags of Our Fathers is a 2006 American war drama film directed, co-produced, and scored by Clint Eastwood and written by William Broyles Jr. and Paul Haggis. It is based on the 2000 book of the same name written by James Bradley and Ron Powers about the 1945 Battle of Iwo Jima, the five Marines and one Navy corpsman who were involved in raising the flag on Iwo Jima, and the after effects of that event on their lives.

The film is taken from the American viewpoint of the Battle of Iwo Jima, while its companion film, Letters from Iwo Jima, which Eastwood also directed, is from the Japanese viewpoint of the battle. Although it was a box office failure, only grossing $65.9 million against a $90 million budget, the film received favorable reviews from critics.The companion film Letters from Iwo Jima was released in Japan on December 9, 2006, and in the United States on December 20, 2006, two months after the release of Flags of Our Fathers on October 20, 2006.

Until June 23, 2016, the author Bradley's father John Bradley, Navy corpsman, was misidentified as being one of the figures who raised the second flag, and incorrectly depicted on the bronze statue memorial, as one of the five flag-raisers of the 32-foot (9.8 m) monument. Also, until October 16, 2019, Rene Gagnon was also misidentified.
