A map of the Jones Falls Watershed

The Jones Falls is a 17.9-mile-long (28.8 km)stream in Maryland. It is impounded to create Lake Roland before running through the city of Baltimore and finally emptying into the Baltimore Inner Harbor.

The Jones Falls valley has a long history in the city of Baltimore as a transportation corridor. The valley of the Jones Falls carries Falls Road, the tracks for the Amtrak Northeast Corridor, the Jones Falls Expressway (JFX) of Interstate 83, and the Baltimore Light Rail. The Baltimore Penn Station also rests on an elevated platform in the valley. It also carries tracks for a historic rail line which is currently served by the Baltimore Streetcar Museum. The MTA Maryland Route 27 also provides transportation on Falls Road; however, at some point it was moved from following 36th Street south to other city streets.

The Jones Falls is spanned by many bridges within Baltimore City's borders, and often the Jones Falls Expressway rests directly above the river.

The Jones Falls begins as a small stream in Baltimore County near Garrison at the intersection of Caves and Garrison Road (39.41771° -76.75750°). It travels southeast for 3.3 miles (5.3 km) before joining the North Branch Jones Falls stream near Stevenson (39.41225° -76.70937°). North Branch Jones Falls originates near Worthington by the intersection of Park Heights Avenue and Walnut Avenue (39.46135° -76.75057°). The North Branch travels south for 5.2 miles (8.4 km) before joining Jones Falls stream. The falls then travels east for 1.3 miles (2.1 km) before Dipping Pond Run joins at ( 39.41424° -76.68557°). The Jones Falls continues east another 0.8 miles (1.3 km) before Deep Run intersects near Brooklandville (39.41467° -76.67060°). The stream then continues south along Interstate 83 (I-83), which is named the Jones Falls Expressway, for 1.7 miles (2.7 km) until Slaughterhouse Branch and Moores Branch join it next to the I-83 overpass over Maryland Route 25 (MD 25, Falls Road) (39.39587° -76.66442°). The Jones Falls travels southeast for 1.5 miles (2.4 km), passing through Robert E. Lee Park, until it meets Lake Roland, an impounding of the stream. (39.39069° -76.64639°) In Lake Roland, Roland Run and Towson Run both join. Once it leaves Lake Roland, the Jones Falls becomes a small river.
