The 1957 NBA playoffs was the postseason tournament of the National Basketball Association's 1956-57 season.
While the Hawks' dominance of the Western Division was succeeded by the Los Angeles Lakers afterward, Boston missed the NBA Finals just once between 1957–1969, and won the NBA title in every year but two.
In the division semifinals, the Philadelphia Warriors were swept by the Syracuse Nationals 2–0.
This was the first time in NBA history that the defending champions were swept in the opening round.
It was also the only time in which the playoff series leading to the Final resulted in sweeps.
