|Elections in Pennsylvania|
The Philadelphia mayoral election of 1851 saw the reelection of Charles Gilpin.
Beginning in 1839, the city operated under a mixed electoral system. Citizens voted for mayor in a general election. If a candidate receive a majority of the vote, they would be elected mayor. However, if no candidate received a majority, the City Council would select a mayor from the top-two finishers.
