Clyde's Restaurant Group is an American company that owns and operates 14 restaurants in the Washington metropolitan area. Founded in 1963 to take advantage of a change in Washington, D.C.'s liquor laws, it pioneered a number of changes in the way restaurants in the district operated. In 1970, it purchased the oldest restaurant in the district, Old Ebbitt Grill. The company has since expanded its namesake "Clyde's" restaurant into a small chain, as well as opened and purchased other restaurants. In 2019, the company was acquired by Graham Holdings.
