Mayors of Philadelphia Timeline

The mayors of Philadelphia since 1952 have all been Democrats. The office was reshaped by the Home Rule Charter of 1951, which created a strong-mayor system with a four-year term and a limit of two consecutive terms. This article lists the charter-era mayors and the defining issues of each administration. For the powers of the office, see Mayor of Philadelphia.^[1]

1 Before the charter

Until 1952 the mayor's office was held by Republicans; the last Republican mayor, Bernard Samuel, served from 1941 until January 1952. That era is summarized in Philadelphia Political History.

2 Mayors 1952-1992

• Joseph S. Clark Jr. (1952-1956): first mayor under the new charter; reform and civil-service emphasis.
• Richardson Dilworth (1956-1962): resigned to run unsuccessfully for governor.
• James H. J. Tate (1962-1972): succeeded as Council president, then won election in his own right; a leader of the Democratic organization.
• Frank L. Rizzo (1972-1980): former police commissioner; polarizing tenure on policing and race.
• William J. Green III (1980-1984): confronted fiscal strain.
• W. Wilson Goode (1984-1992): first Black mayor; the 1985 MOVE confrontation and the late-1980s fiscal crisis marked his tenure.

Dates and order are drawn from official city records and standard reference works.^[1][2]

3 Mayors 1992-2024

• Edward G. Rendell (1992-2000): closed a large deficit with labor concessions and oversight from PICA.
• John F. Street (2000-2008): former Council president; the Neighborhood Transformation Initiative and a federal investigation of City Hall contracting that ended with convictions of associates, not the mayor (see Political Corruption Cases).
• Michael A. Nutter (2008-2016): Great Recession budgets, zoning-code rewrite, and strengthened ethics rules (see Board of Ethics).
• James F. Kenney (2016-2024): enacted the beverage tax for pre-kindergarten, led the city through the COVID-19 pandemic and the 2020 unrest.

4 The Parker administration

Cherelle L. Parker, a Democrat and former Council majority leader, won the May 2023 Democratic primary in a crowded field and the November 7, 2023 general election, defeating Republican David Oh with about 75 percent of the vote to about 24 percent, according to the official results summarized by Wikipedia. She took office on January 1, 2024 as the city's 100th mayor and its first woman mayor. Her stated priorities have included public safety, housing and neighborhood economic development. As of October 2026 she is serving her first term; the next mayoral election is in 2027.^[3]

Because Philadelphia mayors cannot serve more than two consecutive terms, each open-seat election attracts a large field and a multi-million-dollar fundraising race; see Campaign Finance in Philadelphia and Elections in Philadelphia.

Ten Democrats served between Clark and Kenney, and the office has not changed parties since 1952. Because of the two-consecutive-term limit, an open seat attracts a crowded Democratic primary, as in 2023, while incumbents running for a second term have generally prevailed; the Inquirer observed in June 2026 that no Philadelphia mayor has lost a re-election bid in modern history.^[4] The Charter's resign-to-run rule means that sitting city officials who want to run for mayor must resign first, which shaped the 2023 field (see Running for Office in Philadelphia). The next mayoral election is in November 2027, with the primary in May 2027.

Two practical points help in reading the list. First, the dates above refer to terms that begin in the first week of January after a November election, so a mayor elected in November 2023 took office in January 2024. Second, a mayor who leaves early is succeeded by an acting mayor chosen under the Charter's succession rules; the 1962 transition from Dilworth to Tate, who was Council president at the time, was an example. The mayor's relationship with City Council and the independently elected row offices has shaped every administration; see How Philadelphia Government Is Organized.
