Block-Heads is a 1938 American comedy film directed by John G. Blystone and starring Stan Laurel and Oliver Hardy. It was produced by Hal Roach Studios for Metro-Goldwyn-Mayer. The film, a reworking of elements from the Laurel and Hardy shorts We Faw Down (1928) and Unaccustomed As We Are (1929), was Roach's final film for MGM.

Laurel and Hardy were a British-American comedy team during the early Classical Hollywood era of American cinema, consisting of Englishman Stan Laurel (1890–1965) and American Oliver Hardy (1892–1957). Starting their career as a duo in the silent film era, they later successfully transitioned to "talkies". From the late 1920s to the mid-1950s, they were internationally famous for their slapstick comedy, with Laurel playing the clumsy, childlike friend to Hardy's pompous bully. Their signature theme song, known as "The Cuckoo Song", "Ku-Ku", or "The Dance of the Cuckoos" was heard over their films' opening credits, and became as emblematic of them as their bowler hats.
