The Poplar Bluff, Mo., native received all 76 votes and compiled 228 points in the balloting.
"It's quite an honor considering all the great players that have played in the ACC," says Hansbrough. "It's really a tough league year in and year our. If it's not the best league in a given year, it's always one of the best. I don't think in terms of individual awards and accomplishments, but to do something that's never been done before in a league as great as the ACC is pretty cool."
Lawson received 224 votes, the third-most behind Hansbrough and Florida State's Toney Douglas (226). Duke's Gerald Henderson (210) and Miami's Jack McClinton (188) rounded out the first team.
Carolina senior forward Danny Green made third-team and junior Wayne Ellington was an honorable mention pick. Tar Heel rookie Ed Davis earned a spot on the All-Freshman Team.
Green became the fourth Tar Heel to win a spot on the league's All-Defensive Team. He joins Brendan Haywood (2001), Jackie Manuel (2004 and 2005) and Marcus Ginyard (2008) as All-ACC Defensive selections.
Hansbrough and Lawson being on the first team marks the first time UNC has placed two on the first team since 2005 when Raymond Felton and Sean May were selected.
Carolina leads the ACC with 69 first-team selections and 126 all-conference picks. Duke is second with 58 first-team picks and 122 overall.
