The Capt. Salem Avery House is a historic home and museum at Shady Side, Anne Arundel County, Maryland, United States. It is a two-story frame building, located on a 0.75-acre (3,000 m2) rectangular lot, overlooking the West River and Chesapeake Bay. The property consists of the main house with additions; three sheds formerly used as bath houses; and a modern boathouse built in 1993, featuring the locally built EDNA FLORENCE, a 1937 Chesapeake Bay deadrise workboat. The two-story house consists of the original residence, constructed about 1860, which was later expanded the 19th century and in the 1920s, by the National Masonic Fishing and Country Club.
