Tobias Emanuel Petersen (born October 27, 1978) is an American former professional ice hockey right winger who formerly played for the Dallas Stars of the National Hockey League (NHL).

[1] During Game 3 of the Western Conference Final in the 2005–06 playoffs, Petersen scored his first ever NHL playoff goal against Ilya Bryzgalov of the Anaheim Ducks by stealing the puck and wrapping it into an empty net while Bryzgalov attempted to make a play behind his goal line.

The experience began the day before the game when Petersen won the 2008 AHL Skills Competition's fastest skater event with a 14.001 second lap.

[3] In the 2013–14 season, his seventh within the Stars organization, Petersen helped the Texas Stars to claim their first Calder Cup and immediately announced his retirement from professional hockey.

The Wilkes-Barre/Scranton Penguins nominated him as their 2003–2004 AHL Man of the Year candidate for his work with Diabetes charities.
