Kevin Martin, nicknamed "The Old Bear" and "K-Mart", is a Canadian retired curler originally from Lougheed, Alberta and residing in Edmonton. He is an Olympic, World and four-time Canadian champion and a member of the World Curling Hall of Fame. He is considered by many commentators and former and current curlers to be the greatest curler of all time. He is also known for his rivalries with Randy Ferbey/David Nedohin, the best Alberta provincial rivalry ever as the two teams were generally regarded the best in the world from 2002 to 2006; his rivalry with Jeff Stoughton, perhaps the most famous all prairies rivalry ever which spanned over 2 decades from 1991 to 2014; with Glenn Howard from 2007 to 2014, perhaps the best two team rivalry in Canadian curling history, and his rivalry with Sweden's Peja Lindholm from 1997 to 2006, perhaps the best ever men's Canada-Europe rivalry.

Curling is a sport in which players slide stones on a sheet of ice toward a target area which is segmented into four concentric circles. It is related to bowls, boules, and shuffleboard. Two teams, each with four players, take turns sliding heavy, polished granite stones, also called rocks, across the ice curling sheet toward the house, a circular target marked on the ice. Each team has eight stones, with each player throwing two. The purpose is to accumulate the highest score for a game; points are scored for the stones resting closest to the centre of the house at the conclusion of each end, which is completed when both teams have thrown all of their stones once. A game usually consists of eight or ten ends.
