The SEPTA Subway–Surface Trolley Lines are a collection five SEPTA trolley lines that operate on street-level tracks in West Philadelphia and Delaware County, Pennsylvania and also underneath Market Street in Philadelphia's Center City. The lines, Routes 10, 11, 13, 34, and 36, collectively operate on about 39.6 miles (63.7 km) of route.

SEPTA's Route 15, the Girard Avenue Line, is another streetcar line that is designated green on route maps but is not part of the subway-surface system.

Like Boston's Green Line and San Francisco's Muni Metro, the SEPTA Trolley line is the descendant of a pre-World War II streetcar system. Where Boston and San Francisco's systems use longer, articulated LRT vehicles, Philadelphia uses rigid vehicles roughly four inches longer than the PCC streetcar they somewhat replaced. The lines use K-Car LRVs delivered in 1981-82. The cars are similar to those on Routes 101 and 102, SEPTA's suburban trolley routes, which were delivered around the same time. However, the Subway-Surface cars are single-ended and use trolley poles, while the suburban lines operate in couplets.

Starting from their eastern terminus at 13th Street Station near City Hall, the trolleys loop around in a tunnel under City Hall before stopping at under Dilworth Park at 15th Street station and then realign back under Market Street.
