Walter Connolly (April 8, 1887 – May 28, 1940) was an American actor. While some film historians complain that a number of his performances were annoying or overbaked, he was for the most part applauded for his zesty contributions to a number of comedy classics. Frank Capra's Lady for a Day (1933), Broadway Bill (1934) and It Happened One Night (1934), as well as the Carole Lombard/Fredric March screwball farce Nothing Sacred (1937) as news reporter March's hot-headed editor boss are sure-fire examples.

The son of the head of the Western Union relay office, he attended St. Xavier College and the University of Dublin in Ireland before making his New York debut in 1910 in an outdoor presentation of "As You Like It". For the next year or so he was a member of E.H. Sothern's touring company and played supporting roles in a number of Shakespearean shows on the road. After a few silent pictures left him unimpressed with film-making, he turned to the Broadway stage in the 1920s and scored quite well. Somewhat short and tubby, it was not difficult for the jowly, mustachioed actor to seize laughs and he found his share in such outings as "The Talking Parrot" (1923), "Applesauce" (1925), "The Springboard" (1927), "The Happy Husband" (1928), "Stepping Out" (1929), "Your Uncle Dudley" (1930), "Anatol" (1931), "Six Characters in Search of an Author" (1931), "The Good Fairy" (1932) and "The Late Christopher Bean" (1932).
