The 1993 United States Senate special election in Texas was held on June 6, 1993, to replace Democratic U.S. Senator Lloyd Bentsen, who had resigned to become Secretary of the Treasury. Governor Ann Richards appointed Democrat Bob Krueger, a Texas Railroad Commissioner, to fill the seat. Krueger ran in the special election, but was defeated in a landslide by Republican Kay Bailey Hutchison. The nonpartisan blanket primary was held on May 1, 1993. Since no candidate received a majority in the primary, a runoff was held on June 6, 1993.

Robert Charles Krueger was an American diplomat, politician, and U.S. Representative and U.S. Senator from Texas, a U.S. Ambassador, and a member of the Democratic Party. As of 2024, he was the last Democrat to serve as a United States Senator from Texas.
