O-Tora-san (おトラさん O-Tora-san) is a film directed by Motoyoshi Oda. It is the first film in the O-Tora-san series, based on a television program. There were six films total, released in 1957 and 1958. The stories concern "O-Tora-san", a maid, and are apparently unrelated to Shōchiku's later "Otoko wa Tsurai yo" series.
