Walter Brown Arena is a 3,806-seat multi-purpose arena in Boston, Massachusetts. It is home to the Boston University Terriers women's ice hockey team and hosted the men's team before they moved to Agganis Arena. It hosted the first rounds of the 2003 and 2004 America East Conference men's basketball tournaments. It is named in honor of Walter A. Brown, the original owner of the Boston Celtics, former president of the Boston Bruins and second manager of the Boston Garden (after his father).

While it is known as the home of the four men's hockey NCAA championships, one of its most famous (and tragic) events was in October of 1995, when Travis Roy, a 20-year old freshman hockey player, lost his balance attempting to make a check eleven seconds into his first collegiate hockey shift versus North Dakota, breaking his neck at the fourth vertebra and paralyzing him from the neck down. His jersey number, 24, is now retired by the hockey team.
