Louisiana's 28th State Senate district is one of 39 districts in the Louisiana State Senate. It has been represented by Republican Heather Cloud since 2020, succeeding term-limited Democrat Eric LaFleur.
District 28 covers all of Allen and Evangeline Parishes and parts of Acadia, Avoyelles, and St. Landry Parishes, including some or all of Kinder, Oakdale, Ville Platte, Mamou, Eunice, Bunkie, Cottonport, Marksville, and Simmesport.
The district overlaps with Louisiana's 3rd, 4th, and 5th congressional districts, and with the 28th, 32nd, 38th, 40th, and 41st 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.
