The Maine Red Claws are a professional minor league basketball team based in Portland, Maine. The Red Claws compete in the NBA G League and are affiliated with the Boston Celtics.  The team played its first season in 2009–10. The team's home court is the Portland Expo Building. The team is owned by Maine Basketball, LLC, which is chaired by William Ryan, Jr.
On February 25, 2009, the NBA G-League awarded the city of Portland, Maine, with an expansion franchise.  On July 21, 2009, the Red Claws announced Austin Ainge as the first head coach of the team.  During the 2009–10 season, the Red Claws were the only D-League team to sell out all 24 of their home games. This streak continued until the 2011–12 season, ending the streak at 48 consecutive games.
On July 16, 2014, the Red Claws announced that Mike Taylor would not return for a third season as the team's head coach. He had a 45–55 record as coach over two seasons with the team.  He was replaced by Canadian Scott Morrison after 11 seasons as the head coach of Lakehead University's Lakehead Thunderwolves. Morrison spent the 2013–14 season as a D-League assistant.  On June 21, 2017, Brad Stevens, Boston Celtics head coach, named him as an assistant coach with the Celtics. 
On April 2, 2009, "Red Claws" was announced as the winning name after a name-the-team contest. Voters in the contest could choose from the Red Claws, Beacons, Crushers, Destroyers, Swarm and Traps. The name and logo give homage to the lobster fishing industry, a major economic engine of the New England area. The use of "Red" in the team's name also serves to pay tribute to longtime Boston Celtics coach Red Auerbach.
