The 1958 NBA playoffs was the postseason tournament of the National Basketball Association's 1957-58 season. The tournament concluded with the Western Division champion St. Louis Hawks defeating the Eastern Division champion Boston Celtics 4 games to 2 in the NBA Finals.
It was the second straight year the Celtics and Hawks met in the Finals; they met four out of five years, with the Celtics winning three series and the Hawks one.
This was the first (and as of 2020, only) title in Hawks franchise history. St. Louis made it to the NBA Finals four times in five years between 1957-1961, but since moving to Atlanta in 1968, they have had considerably less success in the playoffs.
