1930 United States Senate election in Wyoming

The 1930 United States Senate election in Wyoming was held on November 4, 1930. Following the death of Republican Senator Francis E. Warren, former Casper Mayor Patrick J. Sullivan was appointed to replace him. Sullivan did not seek re-election, however. Following a contested Republican primary, former Governor Robert D. Carey emerged as the nominee, and faced Democrat Harry Schwartz, an attorney from Casper and a local school board member, in the general election. Despite the strong performance by Democrats nationwide in 1930, Carey defeated Schwartz by a wide margin.
