Sailor Beware! is a 1956 British comedy film directed by Gordon Parry and starring Peggy Mount, Shirley Eaton and Ronald Lewis. It was shot at Shepperton Studios with sets designed by the art director Norman G. Arnold. It was released in the United States by Distributors Corporation of America the following year as Panic in the Parlor .

The film is an adaptation of the successful stage play of the same name. It follows the story of a sailor betrothed to be married, but wary that home-life may echo that of her parents: a hen-pecked husband and battle-axe mother. It is one of Michael Caine's first films; he has a small, uncredited role as a sailor.
