Alex Whitmore Brooks (born August 21, 1976 in Madison, Wisconsin) is an American ice hockey defenseman currently playing for Karlskrona HK of the Swedish Division 1. An undrafted player, Brooks played 19 games in the National Hockey League for the New Jersey Devils in 2006–07.

Undrafted and out of college, Brooks took his game to Jokerit of the Finnish First League. The New Jersey Devils, attracted to Brooks' tough defensive play, signed the defenseman to a contract. Brooks spent four years with the Devils' minor league affiliate, the Albany River Rats. When veteran center Pascal Rheaume was traded, Brooks was named captain, and held that post even after the team relocated to Lowell. When several Devils were injured, including Colin White, Johnny Oduya, and Brad Lukowich, Brooks was called up, playing 19 games and scoring 1 assist to go along with 4 PIM. Then, in a game against the St. Louis Blues, Brooks broke his foot, and was subsequently sent back to Lowell, and was replaced by Andy Greene. He returned to Lowell and regained his post as captain. Andy Greene flourished, and thus, Brooks was left in Lowell. On August 9, 2007, Brooks signed on with the St. Louis Blues. However with chances limited, Brooks provided a veteran presence in Peoria, the Blues minor league squad. He played one season with the Chicago Wolves of f the American Hockey League before returning to Finland and Jokerit for the 2009–10 season.
