1957 Los Angeles mayoral election

The 1957 Los Angeles mayoral election took place on April 2, 1957. Incumbent Norris Poulson was re-elected with minimal opposition. Poulson had stated that he would retire from the office before changing his mind and filing for re-election; County Supervisor Kenneth Hahn, President of the Los Angeles City Council John S. Gibson Jr., and advertising executive Don Belding all withdrew after Poulson made his announcement. Four candidates still ran to defeat Poulson, but Poulson won outright in the primary election.

Municipal elections in California, including Mayor of Los Angeles, are officially nonpartisan; candidates' party affiliations do not appear on the ballot.
