Rick DiPietro, Jr. (born September 19, 1981) is an American professional ice hockey goaltender currently playing for the New York Islanders of the National Hockey League (NHL).

DiPietro studied at Saint Sebastian's School but left after his sophomore year to play junior hockey in Michigan. He played one season (1999-2000) with Boston University in the NCAA's Hockey East. In that one year, DiPietro was named to the All-Rookie Team, named Second Team All-Hockey East, awarded the team's Co-MVP and was named Hockey East's Rookie of the Year. In addition, DiPietro nearly set the NCAA record for most saves in a game when he stopped 77 out of 80 shots in a 3-2 quadruple overtime loss to St. Lawrence University during the NCAA regional final (record is 78 and held by Dick Greenlaw). In his one and only Beanpot Tournament, DiPietro was named MVP and won the Eberly Trophy awarded to the tournament's top goaltender.

He was drafted first overall by the New York Islanders in the 2000 NHL Entry Draft, out of Boston University, prompting them to trade Roberto Luongo. Islander GM Mike Milbury traded Luongo, so that he could draft the highly-touted goalie known for his mobility and puck handling skills. DiPietro was the fourth American to occupy the top draft position in the NHL Entry Draft. Though his NHL debut was widely anticipated, and he played 20 games in the 2000-2001 season, he managed to post just 3 wins against 15 losses for a subpar New York team and was sent to the minors for additional seasoning. He played for the Chicago Wolves of the IHL and the Bridgeport Sound Tigers of the AHL. He played 10 games the next season (as well as one playoff game) before being called up for good in the 2003-2004 season. His goals-against average decreased from 3.49 in the 00-01 season to 2.36 in the 03-04 season.
