Keith Aulie (born June 11, 1989) is a Canadian professional ice hockey defenceman currently an unrestricted free agent.

Internationally, Aulie played in the 2009 World Junior Championships, where he paired with Tyler Myers on defence and helped Canada capture a gold medal.

During his first professional season with the Heat, Aulie's rights were traded to the Toronto Maple Leafs, along with Dion Phaneuf and Fredrik Sjöström, in exchange for Matt Stajan, Ian White, Niklas Hagman and Jamal Mayers.

[10] After the Maple Leafs traded defenceman François Beauchemin to the Anaheim Ducks, Aulie was called up to rejoin the team.

[17] As a free agent, Aulie accepted a professional try-out contract to attend the training camp of the Arizona Coyotes on September 9, 2015.

[18] A month into the 2015–16 season, Aulie was signed to a professional try-out contract with the Coyotes AHL affiliate, the Springfield Falcons on November 3, 2015.

[20] Aulie returned to North America in the off-season and belatedly signed a professional try-out contract to begin the 2016–17 season with the reigning Calder Cup champions, the Cleveland Monsters, on October 18, 2016.

He made a return within the Flames organization on November 3, 2016, signing another professional try-out with AHL affiliate, the Stockton Heat.

As a free agent into the 2017–18 season, Aulie again signed late in agreeing to a PTO with the Chicago Wolves of the AHL on October 18, 2017.

[5][27] After the tournament, Aulie was honoured by his hometown of Rouleau with a steak dinner, as well as by his then-NHL team, the Calgary Flames, when he attended a game against the St. Louis Blues.

He attended high school at Athol Murray College of Notre Dame in Wilcox,[6] before he began playing with the Brandon Wheat Kings.

In December 2006, Aulie's father was using a tractor to clear snow off a frozen dugout in anticipation of an outdoor shinny game on New Year's Day.
