The primary election for the 1984 United States Senate election in Louisiana was held on September 29, 1984.

Incumbent Democratic Senator J. Bennett Johnston won the election with 85% of the vote and was declared elected by a majority, dispelling the need for a general election in November. This was despite Republican president Ronald Reagan carrying the state with more than 60% of the vote in the concurrent presidential election.
