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). ESPN was a key part of the creation of the challenge and held the broadcast rights to all the games. The ACC–Big Ten Challenge occurred early in the non-conference season, typically around late November or early December. Each game was hosted by one of the participating schools, with teams typically alternating home and away status in each successive year. The event was played yearly from 1999 to 2022.

The ACC held an overall record of 13–8–3 in the series and 152–127 in the games. The ACC won each of the first 10 consecutive challenges, but the B1G won 8 of the last 14. In the 24 years of the event, 17 of the Challenges were decided by a single game or ended in a tie. Six of the other seven Challenges were won by the ACC by larger margins.

The popularity of the Challenge led other conferences to form similar partnerships in which their members go head-to-head against each other. Examples include the Big 12/Pac-10 Hardwood Series (2007–2010), SEC–Big East Challenge (2007–2012), Mountain West–Missouri Valley Challenge (2009–2018), Big 12/SEC Challenge (2013–2022), Big East–Big 12 Battle (2019–present) and the Gavitt Tipoff Games between the Big East and Big Ten (2015–2022). A sister series to the Challenge featuring women's basketball called the ACC–Big Ten Women's Challenge (2007–2022) was held for all but the first eight years.

The ACC initially played a short-lived interconference basketball series called the ACC–Big East Challenge (1989–1991),ACC-Big East passes test, but won't run its course Last series opens amid ending debate, Baltimore Sun, dated December 2, 1991 and accessed January 12, 2021Faceoff in the ACC-Big East Challenge, Sports Illustrated, 1989, accessed December 1, 2015 Big East coaches such as the late Georgetown coach John Thompson voted to end the ACC–Big East Challenge in 1991, which led to the ACC immediately looking to schedule a new series with the Big Ten as its preferred partner.

On November 28, 2022, amid ESPN losing its media rights to the Big Ten, it was announced that the series would be discontinued after the 2022–23 season. ESPN arranged an ACC–SEC Challenge as a replacement beginning in the 2023–24 season.

Format Typically, match-ups are selected for their expected interest in the game. Higher profile teams are chosen to play each other to enhance television ratings for ESPN. Minnesota and Florida State have had the most matches together, with six games. Seven other pairs of teams have faced each other five times in the Challenge.

With the exception of two years (2011–12), the imbalance of the number of teams in each conference result in up to three teams not playing. Nine games were scheduled for each of the first six challenges, leaving two teams from the 11-team Big Ten without an opponent. With the expansion of the ACC to 12 teams with the addition of Boston College, Miami, and Virginia Tech, the field was expanded to 11 games in 2006, meaning that one ACC team would not play. With Nebraska joining the Big Ten in 2011, the challenge expanded to 12 games and every member from both conferences participated. In 2013, Syracuse, Pittsburgh, and Notre Dame joined the ACC, leaving three ACC teams excluded from the competition. In 2014, Maryland withdrew from the ACC and joined the Big Ten along with Rutgers, giving that conference 14 teams, and Louisville joined the ACC replacing Maryland and maintaining the conference's 15-team membership. These conference realignments have led to the challenge being expanded to 14 games. When the challenge was expanded to 12 games, and later 14 games, the changes resulted in the possibility that the challenge could end in a tie. In the event of a tie, the previous year's winner retained the Commissioner's Cup. This scenario occurred when the ACC retained the Cup in 2018 based on its 11–3 win in 2017, while the Big Ten retained the Cup in both 2012 and 2013 based on its 8–4 win in 2011.
