Geography
District 5 is primarily located in New Orleans, including parts of Carrollton, the Garden District, Mid-City New Orleans, and Uptown New Orleans, stretching to also cover a small part of Jefferson Parish.

The district overlaps with Louisiana's 1st and 2nd congressional districts, and with the 82nd, 91st, 93rd, 97th, and 98th districts of the Louisiana House of Representatives.

At 15 square miles, it is the smallest Senate district in Louisiana.

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.
