Kenneth Howard Delmar (born Kenneth Frederick Fay Howard; September 5, 1910 - July 14, 1984) was an American actor active in radio, films, and animation. An announcer on the pioneering radio news series The March of Time, he became a national radio sensation in 1945 as Senator Beauregard Claghorn on the running "Allen's Alley" sketch on The Fred Allen Show. The character Delmar created was a primary inspiration for the Warner Bros. cartoon character Foghorn Leghorn.

By the late 1930s, Delmar was an announcer on such major radio series as The March of Time and Your Hit Parade. He played multiple roles in The Mercury Theatre on the Air's October 1938 radio drama The War of the Worlds. His main role was that of Captain Lansing of the Signal Corps who dies when 7,000 troops confront the Martian invaders, and also is noted for his address to the "citizens of the nation" as the Secretary of the Interior, in which role he spoke in a stentorian, declamatory style deliberately reminiscent of then-President Franklin Roosevelt. Cavalcade of America featured him in their repertory cast, and also was heard as Commissioner Weston on early episodes of The Shadow.
