The 2019 San Francisco District Attorney election was held on November 5, 2019, to elect the next district attorney of San Francisco. The election, which was held alongside the 2019 mayoral election in which incumbent mayor London Breed won her first full term, was won by public defender Chesa Boudin. The incumbent district attorney, George Gascón, announced in October 2018 that he would not seek a third term. Gascón then abruptly resigned in October 2019, and Breed appointed Suzy Loftus to replace him on an interim basis.
