1972–73 Indiana Pacers season

The 1972–73 Indiana Pacers season was the franchise's sixth season both as a team and in the American Basketball Association. The Pacers entered the season looking to repeat as champions of the ABA, as well as win a record-high third ABA championship in four years after previously winning the ABA Finals in 1970 and 1972. Indiana finished the season by being second place in the Western Division with a 51–31 record, finishing behind only the Utah Stars by four games, before winning their third ABA title in seven games. In a rematch of the 1972 Western Division Semifinals, the Pacers eliminated the Denver Rockets 4–1 this time around after going to seven games with them the last time they met. After defeating the Rockets in five games, the Pacers eliminated the Utah Stars in their 1972 Western Division Finals rematch in six games after previously beating them in seven games last year. The Eastern Division champion Kentucky Colonels appeared in the ABA Championships for the second time in franchise history (with them first apppearing in 1971); while the Colonels would fight tooth and nail with the Pacers, Indiana would ultimately prevail in seven games against their nearby rivals in Kentucky, becoming the only ABA team to ever repeat as champions while the ABA existed as a league.

This is the last ABA season where the Pacers won the championship, and as of 2025, this is the last season the Pacers won a championship of any kind in either the ABA or NBA.
