North Carolina's depth proved to be too much for North Carolina State's determination.
The eighth-ranked Tar Heels beat their Tobacco Road rivals 89-to-80 for their first Atlantic Coast Conference title since 1998.
Brandan Wright and Wayne Ellington scored 16 apiece, Tyler Hansbrough went 11-for-11 from the foul line to finish with 15, and Reyshawn Terry and Ty Lawson added 13 each.
It's North Carolina's 16th A-C-C tournament title, tying Duke for the most in the conference.
The Tar Heels (28-6) also nailed down a Number One seed in the N-C-A-A tournament.
North Carolina State (18-15) reached the title game with an improbable run. It included upsets of second-seeded Virginia, third-seeded Virginia Tech and defending champion Duke, which had won seven of the previous eight A-C-C titles.
