CityLink Purple (abbreviated PR) is a bus route operated by the Maryland Transit Administration in Baltimore and its suburbs.

The line currently runs from the Wal-Mart parking lot in Catonsville to Bullneck Road/Turner's Station Dundalk (the destination sign found on buses) mostly along the corridors of Frederick Road on the west side and Eastern Avenue on the east side, serving the communities of Yale Heights, Pigtown, downtown Baltimore, Fells Point, and Highlandtown.

Service was extended west to Pimlico and east to Sparrows Point after being combined with Route 26, which started operation in 1926 as a separate streetcar line, before its conversion to a shorter shuttle streetcar in 1950, with riders on other parts of the line being diverted to Route 10.

This was initially done because of a road closure, but MTA, finding a demand for bus service on Wise Avenue, did not change the route back.

Service to Sparrows Point, which had low ridership and required a heavy taxpayer subsidy, was no longer provided,[6] and all other short branches on the route were discontinued.

[7] In addition, a portion of the route between Lombard Street and the State Center Metro subway station was eliminated.
