The 2010 The National was the second Grand Slam event of the men's 2009-10 curling season. It was held January 6–10 at the Sleeman Centre in Guelph, Ontario.
The event featured just two international teams, gearing up for the upcoming 2010 Winter Olympics. John Shuster's Team USA failed to make the playoffs while Great Britain's David Murdoch lost in the quarter final. Also, Canada's Olympic representative, Kevin Martin failed to make the playoffs at a Slam for the first time since 2003.
The final game featured Brad Gushue's rink from St. John's, Newfoundland against Randy Ferbey's Edmonton rink. Gushue, who lost last year's event beat Ferbey, and with it won his first Grand Slam title.
Gushue's team won $24,000 out of a total purse of $100,000.
