The Diary of Anne Frank is a 1959 American biographical drama film based on the Pulitzer Prize-winning 1955 play of the same name, which was in turn based on the posthumously published diary of Anne Frank, a German-born Jewish girl who lived in hiding in Amsterdam with her family during World War II. It was directed by George Stevens, a Hollywood filmmaker previously involved with capturing evidence of concentration camps during the war, with a screenplay by Frances Goodrich and Albert Hackett. It is the first film version of both the play and the original story, and features three members of the original Broadway cast.

The Diary of a Young Girl, commonly referred to as The Diary of Anne Frank, is a book of the writings from the Dutch-language diary kept by Anne Frank while she was in hiding for two years with her family during the Nazi occupation of the Netherlands. The family was apprehended in 1944, and Anne Frank died of typhus in the Bergen-Belsen concentration camp in 1945. Anne's diaries were retrieved by Miep Gies and Bep Voskuijl. Miep gave them to Anne's father, Otto Frank, the family's only survivor, just after the Second World War was over.
