Louisiana's 24th State Senate district is one of 39 districts in the Louisiana State Senate. It has been represented by Democrat Gerald Boudreaux since 2016, succeeding Democrat-turned-Republican Elbert Guillory.
District 24 stretches across several majority-black sections of Lafayette, St. Landry, and St. Martin Parishes in Acadiana, including northern Lafayette and some or all of Carencro, Scott, Sunset, Opelousas, Eunice, and Port Barre.
The district overlaps with Louisiana's 3rd, 4th, and 6th congressional districts, and with the 38th, 39th, 40th, 41st, 44th, 46th, and 96th districts of the Louisiana House of Representatives.
Louisiana uses a jungle primary system. If no candidate receives 50% in the first round of voting, when all candidates appear on the same ballot regardless of party, the top-two finishers advance to a runoff election.
