507 Long Branch is an east–west Toronto streetcar route in Ontario, Canada, operated by the Toronto Transit Commission (TTC). It runs along Lake Shore Boulevard between Humber Loop and Long Branch Loop (just west of Browns Line, adjacent to Long Branch GO Station). It operates entirely within Toronto's Etobicoke district. After 10 pm, 507 Long Branch is replaced by a westward extension of the 501 Queen from Humber Loop to Long Branch Loop. Overnight, 301 Queen, part of the TTC's Blue Night Network service, replaces both 501 Queen and 507 Long Branch, operating from approximately 1 am to 5 am between Neville Park Loop and Long Branch loop. The rush-hour 508 Lake Shore route overlaps 507 Long Branch west of Humber Loop.^[2]

The Long Branch route originally operated from 1935 to 1995, and was numbered "507" when the CLRV streetcars were put into service beginning in 1979. Between 2016 and 2020, the 501 Queen route had a branch that operated like the 507 streetcar but was signed as route 501 Queen.^[3] On November 19, 2023, the TTC split the 501 Queen route, rebranding the portion west of Humber Loop as 507 Long Branch.^[2]
