Louisiana's 21st State Senate district is one of 39 districts in the Louisiana State Senate. It has been represented by Republican Bret Allain since 2012.

Geography District 21 covers all of St. Mary Parish and parts of Iberia, Lafourche, and Terrebonne Parishes along the Gulf of Mexico in Acadiana, including some or all of Thibodaux, Houma, Morgan City, Berwick, Patterson, Franklin, Baldwin, Bayou Vista, and Jeanerette.

The district overlaps with Louisiana's 1st, 3rd, and 6th congressional districts, and with the 46th, 49th, 50th, 51st, 52nd, 53rd, and 55th districts of the Louisiana House of Representatives.

Recent election results 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.
