1948 United States Senate election in Oklahoma

The 1948 United States Senate election in Oklahoma took place on November 2, 1948. Incumbent Republican Senator Edward H. Moore declined to run for re-election. A crowded Democratic primary, including the former Governor, multiple members of Congress, and several statewide elected officials, developed; former Governor Robert S. Kerr won a slim plurality in the initial primary and then defeated former Congressman Gomer Smith by a wide margin in the runoff. On the Republican side, Congressman Ross Rizley had an easy path to the nomination. Kerr defeated Rizley in a landslide, largely similar to President Harry S. Truman's landslide victory in Oklahoma over Republican presidential nominee Thomas E. Dewey.
