The Lowell Devils were a minor league ice hockey team in the American Hockey League playing in Lowell, Massachusetts, at the Tsongas Center.

The team was founded in 1998 as the Lowell Lock Monsters and was purchased by the Devils in 2006.

Founded as the Lowell Lock Monsters in 1998, the team served as the top AHL affiliate of the New York Islanders for three seasons, the last of which was shared with the Los Angeles Kings.

In Lowell, the Devils averaged 2,293 fans per game during the 2008–09 season while receiving the AHL Excellence Award for the Eastern Conference for group sales.

They eventually struck an agreement with Albany, who was to lose the River Rats after the Hurricanes elected to move their top minor league affiliate to Charlotte, North Carolina, as the Charlotte Checkers.
