ACC–Big Ten Challenge

The ACC–Big Ten Challenge (or Big Ten–ACC Challenge as it was called in alternating years) was an in-season NCAA Division I men's college basketball series that matched up teams from the Atlantic Coast Conference (ACC) and the Big Ten Conference (B1G).

Each game was hosted by one of the participating schools, with teams typically alternating home and away status in each successive year.

The popularity of the Challenge led other conferences to form similar partnerships in which their members go head-to-head against each other.

With Nebraska joining the Big Ten in 2011, the challenge expanded to 12 games and every member from both conferences participated.

Duke was the most successful team in either conference in Challenge competition by a large margin, holding a 20–4 record.
