Mark Nichols, ONL (born January 1, 1980) is a Canadian curler from St. John's, Newfoundland and Labrador.

He also won Gold in the 2006 Winter Olympic Games in Turin, at which he threw a spectacular shot - running back a guard onto another stone which picked another rock that was sitting in a dead zone - in the 6th end of the final against Finland, helping Canada to score 6.

Certainly, one thing to aid their victory was the fact that Nichols shot a blistering 97 percent in the gold medal final.

Nichols has won a career total of twelve Grand Slam of Curling events, ten with Gushue and two with Stoughton.

He won two Masters (2014, 2017), two Canadian Open's (2014, 2017), two Elite 10's (2016, 2018 (Sept.)) and one Tour Challenge, Players' Championship and Champions Cup.

He briefly retired from curling after the 2011 Brier, although he always suggested he might return at some point, which he did for the 2012-2013 season as Jeff Stoughton's lead.

Nichols also skipped team Newfoundland and Labrador with sister Shelley, Brent Hamilton and Jennifer Guzzwell to a Canadian Mixed Curling Championship in 2005.
