The 2015 Louisiana Attorney General election took place on October 24, 2015, to elect the Attorney General of the U.S. state of Louisiana, with a runoff election, held on November 21, 2015. Incumbent Buddy Caldwell, a former Democrat who joined the Republican Party in February 2011, sought re-election to a third term in office, but was defeated by fellow Republican Jeff Landry.
Under Louisiana's jungle primary system, all candidates will appear on the same ballot, regardless of party affiliation; voters may vote for any candidate, regardless of their own party affiliation. Since no candidate received a majority of the vote during the primary election, a runoff election was held on November 21, 2015, between Caldwell and Landry. Louisiana is the sole state that has a jungle primary system (California and Washington have a similar "top two primary" system).
