Crisfield Historic District is a national historic district at Crisfield, Somerset County, Maryland, United States. It consists of a cohesive collection of houses, churches, and commercial buildings dating primarily from about 1870 to 1930. They reflect the rapid growth of the town as the center of the booming Chesapeake Bay oyster industry during that period. The district encompasses much of Crisfield's main residential and commercial areas, locally known as "uptown." The Crisfield Armory is located within the district boundaries. It was added to the National Register of Historic Places in 1990.
