Petworth is a neighborhood in the Northwest quadrant of Washington, D.C. Two sets of real estate developers purchased the lands of the Petworth estate and the Marshall Brown estate. The neighborhood bloomed with the expansion of the streetcar line up Georgia Avenue (then known as Seventh Street Extended or Brightwood Avenue) from Florida Avenue (Boundary Street) to the Washington DC line at Silver Spring, Maryland. Today, the neighborhood is primarily residential with a mix of townhouses and single-family homes. It is served by the Georgia Ave-Petworth station on the Washington Metro Green line.

Brightwood is a neighborhood located in the northwestern quadrant of Washington, D.C.

As with most neighborhoods in Washington, D.C., the boundaries of Brightwood are difficult to define. They are roughly Walter Reed Army Medical Center and Aspen Street to the north, 13th Street to the west, 5th Street to the east, and Military and Missouri Avenues to the south. Nearby neighborhoods include Shepherd Park to the north, Takoma to the northeast, 16th Street Heights to the west, and Petworth to the south. Rock Creek Park is also within walking distance to the neighborhood.

Much of the retail in the neighborhood lies along Georgia Avenue. Although no Metrorail stations lie within the neighborhood, the Takoma Metrorail station is within walking distance from the northern part of the neighborhood.
