The 2010–11 Atlantic Coast Conference men's basketball season was the 58th season for the league.

The AP preseason All-American team was named on November 1. Duke's Kyle Singler was the leading vote-getter with 62 of a possible 65 votes. North Carolina forward Harrison Barnes received 17 votes and became the first freshman in history to be named to the preseason team.^[3]

Duke coach Mike Krzyzewski won his 800th game at Duke on November 24, making him the fifth ever coach to reach that milestone at one school.^[4] Kyle Singler^[5] and Virginia Tech guard Malcolm Delaney each passed the 2,000 point mark for their careers.

Duke was the preseason #1 in the AP and ESPN/USA Today Coaches Polls while North Carolina was ranked #9 and Virginia Tech was #23.^[6]
However, Duke later dropped to #3 and then #5, but eventually regained the #1 ranking for one week before dropping again to #4.
North Carolina dropped out of the rankings after week 3 and Virginia Tech dropped out after week 2 leaving Duke as the only ACC school in the top 25 until week 11 when Florida State spent one week at #22 before dropping back out of the rankings.
North Carolina reappeared at #24 in week 12 and has since moved up to #6.
