The 1998 United States Senate elections were held on November 3, 1998, with the 34 seats of Class 3 contested in regular elections. This was seen as an even contest between the Republican Party and Democratic Party. While the Democrats had to defend more seats up for election, Republican attacks on the morality of President Bill Clinton failed to connect with voters and anticipated Republican gains did not materialize. The Republicans picked open seats up in Ohio and Kentucky and narrowly defeated Democratic incumbent Carol Moseley Braun (Illinois), but these were cancelled out by the Democrats' gain of an open seat in Indiana and defeats of Republican Senators Al D'Amato (New York) and Lauch Faircloth (North Carolina). The balance of the Senate remained unchanged at 55–45 in favor of the Republicans.

With Democrats gaining five seats in the House of Representatives, this marked the first time since 1934 that the party not in control of the White House failed to gain congressional seats in mid-term election cycles, which would also happen in 2002. These are the last Senate elections that resulted in no net change in the balance of power, the last time Democrats won a U.S. Senate race in South Carolina, and the last time both major parties were on the general election ballot in every race.
