The Indiana Pacers have never won an NBA championship since joining the National Basketball Association through the 1976 ABA-NBA merger. However, during their earlier years in the American Basketball Association before merging into the NBA, the franchise experienced immense success, capturing three ABA championship titles in 1970, 1972, and 1973 under legendary coach Slick Leonard. Since transitioning into the NBA, the franchise has reached deep playoff rounds, including a memorable appearance in the 2000 NBA Finals, but the elusive NBA championship trophy has remained out of reach.
