Gordon Leo McDonough (January 2, 1895 – June 25, 1968) was an American politician who served as a U.S. Representative from California from 1945 to 1963.

To boost the chances for re-election for Republican colleagues and opportunities for potential new Republican House members, McDonough ran in a newly drawn but unfavorable district against Democrat Edward Roybal, a member of the Los Angeles City Council.

McDonough appeared on the Groucho Marx game show You Bet Your Life on January 4, 1950.

[citation needed] He died in Bethesda, Maryland, June 25, 1968, and was interred in Holy Cross Mausoleum, Los Angeles, California.
