The 1990 United States Senate election in Tennessee was held on November 6, 1990, to select the
U.S. Senator from the state of
Tennessee. Incumbent Senator
Al Gore won re-election to a second term in a landslide, sweeping every county in the state.
As of 2024, this was the last time the Democrats won a U.S. Senate election in Tennessee, and also the most recent U.S. Senate election in Tennessee in which several counties, including
Knox County and
Hamilton County, went to the Democratic candidate.
