Matthew O. McHugh (January 22, 1894 – February 22, 1971) was an American film actor who appeared in more than 200 films between 1931 and 1955, primarily in small cameo parts.

McHugh came from a theatrical family. His parents ran a stock theatre company and, as a young child, he performed on stage. His brother, Frank, who went on to become part of the Warner Bros. stock company in the 1930s and 1940s, and sister Kitty performed an act with him by the time he was fourteen years old, but the family quit the stage around 1930. His brother Ed became an agent in New York.

Matt made his Broadway debut in Elmer Rice's Street Scene in 1929, along with his brother Ed, and also appeared in Swing Your Lady in 1936.

Despite his actual origins, McHugh usually performed his roles with a Brooklyn accent, and was often cast as characters explicitly from Brooklyn. In Star Spangled Rhythm (1941), his one scene is a protracted monologue during the climactic "Old Glory" sequence, in which McHugh plays a character who literally embodies the spirit of Brooklyn.
