Cannon Club, also known as Cannon Dial Elm Club, is one of the historic Eating Clubs at Princeton University. Founded in 1895, it completed its current clubhouse in 1910. The club closed in the early 1970s and later merged with Dial Lodge and Elm Club to form Dial, Elm, Cannon (DEC), which closed its doors in 1998. In 2011 DEC reopened, now bearing the name Cannon Dial Elm Club, using its historic clubhouse, which had served as the home for the Office of Population Research during the club's hiatus.
