Alexander Auld (born January 7, 1981) is a Canadian professional ice hockey goaltender currently playing for the Dallas Stars of the National Hockey League (NHL). Auld has also played for the Vancouver Canucks, Florida Panthers, Phoenix Coyotes, Boston Bruins and Ottawa Senators of the NHL. He has appeared internationally for Team Canada on three occasions – the 2001 World Junior Championships, the 2004 Spengler Cup, and the 2006 World Championships.

Auld started his junior career with the North Bay Centennials of the Ontario Hockey League (OHL) at the tail end of the 1997–98 season, appearing in six games without registering a win. After appearing in 38 games the following season, Auld was selected in the second round, 40th overall, of the 1999 NHL Entry Draft, by the Florida Panthers. Auld would finish out his junior career with the Centennials, spending two more seasons as their starting netminder. In his final season, Auld was named to Team Canada for the 2001 World Juniors, where he backed up Maxime Ouellet. Later that same season, Auld was traded to the Vancouver Canucks for a third round pick in the 2002 NHL Entry Draft and a compensatory pick in the 2001 NHL Entry Draft.

Auld turned professional in the 2001–02 season, joining the Canucks' American Hockey League (AHL) affiliate, the Manitoba Moose. An ankle sprain sidelined Auld during training camp, however, and upon his return he was assigned to the Columbia Inferno of the East Coast Hockey League. Solid play in six games at that level returned Auld to the AHL, where he showed steady improvement, despite competition for playing time from veterans Alfie Michaud and Wade Flaherty. Following injuries to Canucks goaltenders Dan Cloutier and Peter Skudra, Auld got a start at the NHL level, a 4–2 victory over the Dallas Stars on January 23, 2002, after which he returned to the AHL.
