The 1955 NBA playoffs was the postseason tournament of the National Basketball Association's 1954-55 season. The tournament concluded with the Eastern Conference champion Syracuse Nationals defeating the Western Conference champion Fort Wayne Pistons 4 games to 3 in the NBA Finals.
This was the only title for the Nationals under that moniker; the franchise won its next title in 1967 as the Philadelphia 76ers.
For the Pistons, this was their first trip to the NBA Finals in franchise history; they returned the next year, but didn't win their first title until 1989 as the Detroit Pistons.
After experimenting with a round robin playoff format in 1954, the NBA moved to a system in which the top team in each conference earned a first-round bye, giving them the right to start out in the division finals. It remained in place until 1967, when it changed to an eight-team format in which all teams played the first round.
