Jean-Sébastien Aubin (born July 19, 1977) is a Canadian professional ice hockey goaltender who plays for the Philadelphia Phantoms of the American Hockey League (AHL).
Aubin played his junior career in the Quebec Major Junior Hockey League, following in the footsteps of so many other Quebec-born goaltenders. He played for three different teams, spending the most time with the Sherbrooke Faucons. He was drafted in the third round of the 1995 NHL Entry Draft, 76th overall, by the Pittsburgh Penguins. His professional career began in the East Coast Hockey League, but he worked his way on to the Penguins' farm team, and then into the NHL itself.
Aubin played parts of six seasons with Pittsburgh, including one as their starting goaltender, before being released by them. He then signed a two-way contract with the Toronto Maple Leafs. He played his first game with the Maple Leafs on March 26, 2006 on new Jersey, making 36 saves and winning the game 4–3. He recorded a shutout in only his third game with the Maple Leafs, against the Buffalo Sabres in a 7–0 victory on home ice.
