The 2018 United States Senate election in Mississippi took place on November 6, 2018, in order to elect a member of the United States Senate to represent the state of Mississippi. Incumbent Republican Roger Wicker was re-elected to a second full term, defeating his Democratic challenger, David Baria.

The candidate filing deadline was March 1, 2018, and the primary election was held on June 5, 2018, with a runoff on June 26 if a party's primary failed to produce a majority winner.
