Route 23 is a former streetcar line and current bus route. It is operated by the Southeastern Pennsylvania Transportation Authority (SEPTA) in Philadelphia, Pennsylvania, United States. The line runs between the Chestnut Hill and Center City neighborhoods via Germantown Avenue, 11th, and 12th Streets.

Route 23 was once Philadelphia's longest streetcar route,^[4] extending south to 11th St. and Pattison Avenue in South Philadelphia, and was one of three suspended by SEPTA in 1992. A restoration of trolley service has been proposed in recent years, with a feasibility study planned between 2021 and 2027.^[5] Route 23 was also believed to be the longest trolley route within a city in the world.^[4]

The route is consistently one of SEPTA's most heavily-traveled bus lines, coming in as the fourth-busiest for daily ridership in 2018, as well as an average weekday ridership of 14,322.^[1]
