Hollins–Roundhouse Historic District is a national historic district in Baltimore, Maryland, United States. It is a primarily residential area characterized by 19th century rowhouses.

Later, from the 1880s to the 1920s, the neighborhood became established as the center of Baltimore's Lithuanian immigrant community.
