The Battle 4 Atlantis is an early-season college basketball tournament. It takes place at Atlantis Paradise Island on Paradise Island in The Bahamas, on the week of the US holiday of Thanksgiving. For sponsorship purposes, the tournament is officially named Marriott Bonvoy Battle 4 Atlantis. The games are played in the Imperial Arena, a grand ballroom which is turned into a basketball venue. The tournament is known for being the richest Division I men's early-season college basketball tournament. Schools are awarded $2 million in exchange for their participation in the men's event.
In 2020, the tournament was canceled due to the COVID-19 pandemic, which was scheduled to include a women's Battle 4 Atlantis tournament which also would have featured eight teams.
