The 2003 Philadelphia mayoral election was a contest between Democratic incumbent John F. Street and Republican businessman Sam Katz.

Pennsylvania governor and former mayor of Philadelphia Ed Rendell played a key role for Street by ensuring that business interests did not support Katz.{{cite web| title = The PA Report "Power 75" List| work = Pennsylvania Report| publisher = Capital Growth, Inc.| date = January 31, 2003| url = http://www.pa-report.com/uploaded_pdf/PAReportPower75_.pdf| archive-url = https://web.archive.org/web/20060920200116/http://www.pa-report.com/uploaded_pdf/PAReportPower75_.pdf| archive-date = 2006-09-20| format = PDF| quote = ""Governor Rendell's squeezing business not to support Republican nominee, Sam Katz, will help""| url-status = dead}}

The race was covered in the documentary film The Shame of a City. This was the last election prior to the 2019 election that saw a Republican nominee carry a ward, with Katz carrying several.
