The 1958 United States Senate elections were elections for the United States Senate which occurred in the middle of President Dwight D. Eisenhower's second term. As is common in mid-term elections, the party in the White House lost seats, but losses this year were heavy due to the Recession of 1958, the Eisenhower Administration's position on right-to-work issues that galvanized labor unions which supported Democrats, and the launch of Sputnik. This was the first time since 1934 that Democrats gained seats in this class of Senators. Democrats won both seats in West Virginia, making the last time that Democrats simultaneously flipped both of a state's Senate seats until Georgia's elections in 2020 and 2021.
