North Carolina took the lead midway through the second half and was up 67-60 on Kendall Marshall's three-pointer with 3:59 left. Florida State rallied to take a 70-69 lead with 18 seconds left on two free throws by Derwin Kitchen, who led the Seminoles (20-9, 10-5) with 13 points.
Florida State turned the ball over before getting off a final shot after Barnes' game-winner.
The Tar Heels can clinch the top seed in next week's ACC tournament win a win over No. 4 Duke Saturday.
