The 1920 United States Senate election in Oklahoma took place on November 2, 1920. Incumbent Democratic Senator Thomas Gore ran for re-election to a third term. However, he was defeated in the Democratic primary by Congressman Scott Ferris. In the general election, Ferris faced fellow Congressman John W. Harreld, the Republican nominee. Likely helped by Republican presidential nominee Warren G. Harding's victory in Oklahoma over Democratic nominee James M. Cox, Harreld defeated Ferris by a similar margin to Harding's.
