Louisiana's 34th State Senate district is one of 39 districts in the Louisiana State Senate. It has been represented by Democrat Katrina Jackson since 2020.
District 34 covers a majority-black swath of North Louisiana, including all of East Carroll, Madison Parishes, and Tensas Parishes, and parts of Concordia, Morehouse, Ouachita, Richland Parishes. The district covers some or all of the towns of Lake Providence, Tallulah, Ferriday, Delhi, Rayville, Bastrop, Monroe, and Richwood.
The district is located entirely within Louisiana's 5th congressional district, and overlaps with the 14th, 16th, 17th, 19th, 20th, and 21st 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.
