The 1930 United States Senate special election in Kansas was held on November 4, 1930. After Republican Senator Charles Curtis was re-elected in 1926, he was elected Vice President on a ticket with Herbert Hoover in 1928 and resigned his seat in the Senate. Governor Clyde M. Reed, a Republican, appointed former Governor Henry J. Allen to the seat. At the ensuing special election, Allen won a contested Republican primary and then faced former Sedgwick County Attorney George McGill, the Democratic nominee, in the general election. In a nationwide Democratic landslide, McGill narrowly defeated Allen.
