Lutherville Historic District is a national historic district in Lutherville, Baltimore County, Maryland, United States. It is an irregularly shaped urban entity founded in 1852 as a summer resort and suburb of Baltimore City. Single-family dwellings on large lots characterize the community and most of the structures predate World War I, although ranch-type and "colonial" houses have appeared in the past few decades. It was added to the National Register of Historic Places in 1972.
