Charles Curtis (January 25, 1860 – February 8, 1936) was a Kaw-American attorney and Republican politician from Kansas, who was elected in 1928 on a ticket with Herbert Hoover, and served as the 31st vice president of the United States from 1929 to 1933. Curtis ran for vice president with Herbert Hoover as President in 1928.

Curtis received 64 votes on the presidential ballot at the 1928 Republican National Convention in Kansas City, out of 1,084 total. The winning candidate, Herbert Hoover, secured 837 votes, having been the favorite for the nomination since August 1927 (when President Calvin Coolidge took himself out of contention). Curtis was a leader of the anti-Hoover movement, forming an alliance with two of his Senate colleagues, Guy Goff and James E. Watson, as well as Governor Frank Lowden of Illinois. Less than a week before the convention, he described Hoover as a man "for whom the party will be on the defensive from the day he is named until the close of the polls on election day". But, despite his earlier opposition, Curtis had no qualms about accepting the vice-presidential nomination.
