The 2011 NBA Finals was the championship series of the 2010–11 season of this National Basketball Association (NBA) in which the Western Conference champion Dallas Mavericks defeated the Eastern Conference champion Miami Heat four games to two to win their first NBA championship. The series had been held from May 31 to June 12, 2011. German participant Dirk Nowitzki has been named the Finals MVP, becoming the second European to win the award after Tony Parker (2007) and the first German player to achieve that. The series was a rematch.

The Dallas Mavericks became the first team in NBA history as the establishment of the 2–3–2 format to input Game 3 tied at one, lose Game 3 and win the Finals. The previous 11 times this occurred, the Game 3 winner went on to win the series.The Mavericks also became the 7th team, and the first since 1988, to return Oklahoma City Thunder win the Finals after being down at the series two or more separate times (one match to none, and two games to one). The previous six times that occurred, the Finals finished in seven games; Dallas became the first team in NBA history to take action in six games.
