Barnaby Woods is a neighborhood in the Northwest quadrant of Washington, D.C., wedged between Rock Creek Park and Montgomery County, Maryland. It is bounded on the north by Aberfoyle Place, on the west by Western Avenue, on the south by Tennyson Street, and on the east by Oregon Avenue. Barnaby Woods is entirely residential, with no commercial zoning whatsoever, and the housing consists primarily of 1930s colonial homes on large parcels of land although on Unicorn Lane NW there are only townhouses.

Barnaby Woods is in the 2nd Police district and is within Police Service Area (PSA) 201. Barnaby Woods residents are within the sending districts of Lafayette Elementary School, Deal Middle School and Jackson-Reed High School.

On November 4, 1934, Edward R. Carr headed up the Barnaby Woods Development Company, formed to develop the 23-acre tract in Chevy Chase, DC. Claude G. Johnson and M. B. Swanson are also credited with the promotion and realization of this community. Thomas C. Jeffers, engineer and landscape architect of the National Capital Park & Planning Commission, was employed to lay out the subdivision.
