L'Enfant Plaza is a complex of four commercial buildings grouped around a large plaza in the Southwest section of Washington, D.C., United States. Immediately below the plaza and the buildings is La Promenade shopping mall. The plaza is located south of Independence Avenue SW between 12th and 9th Streets SW. It was built perpendicular to L'Enfant Promenade, a north-south running street and pedestrian esplanade part of which is directly above 10th Street SW. The plaza is named for Pierre Charles L'Enfant, the architect and planner who first designed a street layout for the capital city.
