Josh King had put the 'Cherries' ahead with a first half penalty and it looked as if the game was destined to stay that way.
However, a foul late in the game gave Mahrez a dead ball on the edge of the box and he didn't pass up his opportunity.
Left-footed, he struck a low effort around the wall and curving into the bottom corner to break Bournemouth hearts.
