Attack, also known as Attack!, is a 1956 American war film directed by Robert Aldrich and starring Jack Palance, Eddie Albert, Lee Marvin, William Smithers, Robert Strauss, Richard Jaeckel, Buddy Ebsen and Peter van Eyck. The cinematographer was Joseph Biroc.

"A cynical and grim account of war", the film is set in the latter stages of World War II and tells the story of a front-line combat unit led by a cowardly captain clearly out of his depth, as well as a tougher subordinate and an executive officer who both threaten to do away with him. As the official trailer put it: "Not every gun is pointed at the enemy!"

The film won the 1956 Italian Film Critics Award.
