Makarova, a left hander ranked 18th in the world, had fallen in four prior major quarter-finals.
But she out-played two-time Australian Open champion Azarenka, who was runner-up to Serena Williams at Flushing Meadows each of the past two years but has been slowed by injury in 2014.
Makarova will face either world number one and five-time champion Serena Williams or Italian Flavia Pennetta for a place in the final.
