The 1932 United States Senate election in Oklahoma took place on November 8, 1932. Incumbent Democratic senator Elmer Thomas ran for re-election to a second term. Thomas faced a crowded path to renomination, and only won the Democratic primary following a runoff election with attorney Gomer Smith. On the Republican side, oil magnate Wirt Franklin similarly won the Republican nomination in a runoff election. Thomas overwhelmingly defeated Franklin to win re-election, aided by Democratic presidential nominee Franklin D. Roosevelt's landslide win in Oklahoma over Republican president Herbert Hoover.
