1959 Philadelphia municipal election

1959 Philadelphia's municipal election, held on November 3, involved contests for mayor, all seventeen city council seats, and several other executive and judicial offices. Citywide, the Democrats took majorities of over 200,000 votes, continuing their success from the elections four years earlier. Richardson Dilworth, who had been elected mayor in 1955, was re-elected over Republican nominee Harold Stassen. The Democrats also took fifteen of seventeen city council seats, the most seats allowed to any one party under the 1951 city charter. They further kept control of the other citywide offices. The election represented a continued consolidation of control by the Democrats after their citywide victories of the previous eight years.
