Chelmsford Forum

The Chelmsford Forum is a multi-use indoor sport and concert venue, actually located in Billerica, Massachusetts, United States, just across the town line. The venue was formerly home to the UMass Lowell River Hawks, during which time the team won two NCAA Division II national championships (1981 and 1982). It is also home to the ice hockey team from Chelmsford High School.

The arena was formerly named for state senator B. Joseph Tully.
