The Big East–Big 12 Battle is an annual NCAA Division I men's college basketball series in which teams from the Big East Conference face the teams of the Big 12 Conference.^[1][2] The series has been played annually since 2019.^[3] The Big East–Big 12 Battle originally was planned as a four-season competition to be played annually from 2019 through 2022, but on August 1, 2022, the two conferences announced a two-year extension of the series, with games also to be played in 2023 and 2024.^[4]

In 2019, when the Big East consisted of 10 teams, all 10 Big East teams faced one of the 10 Big 12 teams. The Big East expanded to 11 teams when UConn moved from the American Athletic Conference to the Big East for the 2020–2021 season, so from 2020 through 2022 ten of the 11 Big East teams faced one of the Big 12 teams and one Big East team did not participate. The Big 12 added four new schools to the conference in 2023, allowing all 11 Big East teams to participate each season, while three of the 14 Big 12 teams did not. With the Big 12 expanding to 16 teams in 2024, five of its teams will now sit out.^[4]

In the 10-game format used from 2019 to 2022, each conference hosted five games each season. In the 11-game format for 2023 and 2024, the Big 12 hosted six games in 2023 and the Big East will host six in 2024.^[4]

Unlike the now-defunct Big 12/SEC Challenge, the teams in the Big East-Big 12 Battle do not face each other all on the same day. Instead, they play each other over the span of as much as two and a half weeks, with games scheduled in late November and December in some years and solely in December in others. The Big East won the first series 8–2 in 2019, the next three series ended in a tie between the two conferences, and the Big 12 won the 2023 series 7–4.

Four games of the 2020 series were canceled due to the COVID-19 pandemic.

Big 12 home games air on ESPN, ESPN2, ESPNU, ESPN+, and ABC, while Big East home games air on Fox and Fox Sports 1.
