Bobby Ryan (born Bobby Stevenson on March 17, 1987, in Cherry Hill, New Jersey) is an American professional ice hockey player currently playing for the Anaheim Ducks of the National Hockey League (NHL). He was drafted 2nd overall in the 2005 NHL Entry Draft by the Anaheim Ducks.

After winning national championships with his minor hockey team, the Los Angeles Junior Kings, he initially committed to playing for the U.S. National Under-18 Program. Despite telling Ontario Hockey League (OHL) teams he would not play major junior, Ryan was selected by the Owen Sound Attack 7th overall in the 2003 OHL Selection Draft. He was convinced to play for the team and immediately began his major junior career with a 39-point rookie campaign in 2003–04. After improving to 89 points the following season, Ryan was drafted second overall by the Anaheim Ducks in the 2005 NHL Entry Draft

Ryan closed out his OHL career after the 2006–07 season. Upon elimination in the playoffs, he was assigned by the Ducks to the Portland Pirates of the American Hockey League (AHL) for the final 8 games of the AHL season. Ryan then started the 2007–08 season with the Ducks, scoring his first NHL goal in his debut against the Los Angeles Kings at the The O2 arena in London, England. Ryan was, however, sent back to the AHL to Portland after 4 games. He was recalled on March 7, 2008, when Corey Perry's leg injury sidelined him for the remainder of the regular season.
