The mayor of Pittsburgh is the chief executive of the government of the city of Pittsburgh, Pennsylvania, United States, as stipulated by the Charter of the City of Pittsburgh.^[2]

Prior to the 1816 city charter, the Borough of Pittsburgh had its council elect a chief burgess among themselves. After the borough was rechartered as a city, its first seven mayors were selected in a similar fashion as the chief burgesses had been under borough council. It was not until Mayor Samuel Pettigrew in the 1830s that general elections of popular vote were conducted among all the city's voters to determine who would hold the mayor's office. Pettigrew was both the last mayor selected by council and the first generally elected mayor of Pittsburgh. From 1901 to 1903 the state legislature took control of the city on the grounds of corruption by former Mayor William J. Diehl with the passage of the so-called "ripper bill" and appointed the unelected "recorders" Joseph Brown and Adam Brown, who were answerable only to the state government. Since 1903, all mayors have been popularly elected. The mayor as of January 2022^[update] is Democrat Ed Gainey.
