Crawford started every playoff game for Chicago last season, helping the Blackhawks win their second Stanley Cup title in three years. He went 16-7 with an NHL-best 1.84 goals-against average in the postseason.
The Blackhawks announced the deal on Monday. The contract runs through the 2019-20 season.
The 28-year-old Crawford was selected by Chicago in the second round of the 2003 draft. Crawford, who made his NHL debut in January 2006, is 83-43 with eight shutouts, a 2.40 goals-against average and a .913 save percentage in 152 career games with the Blackhawks.
