The Mount Vernon Triangle Historic District is a historic district in the Mount Vernon Triangle neighborhood of Washington, D.C., consisting of 22 contributing residential, commercial, and industrial buildings, and one known archaeological site. The area was once a working class neighborhood for mostly German immigrants and home to semi-industrial enterprises such as a dairy and an automobile repair shop. The Northern Liberty Market that once stood on the corner of 5th Street and K Street NW played a large role in spurring development in the surrounding area as did the streetcars on Massachusetts Avenue and New York Avenue.
The historic district was added to the District of Columbia Inventory of Historic Sites in 2005 and the National Register of Historic Places in 2006. The 22 buildings in the district were constructed between 1869 and 1946. Two of the buildings included in the historic designation process, 470 and 472 K Street NW, collapsed in 2014. Many of the buildings in the district have undergone a restoration process. Prather's Alley, which was once lined with dwellings, stables, and industrial businesses, is being redeveloped into a place for community residents to gather.
