The 1959 NBA playoffs was the postseason tournament of the National Basketball Association's 1958-59 season. The tournament concluded with the Eastern Division champion Boston Celtics defeating the Western Division champion Minneapolis Lakers 4 games to 0 in the NBA Finals. It was the Celtics' second NBA championship. This was the first NBA Finals matchup between the Lakers and Celtics; as of 2020, they have met in the Finals 12 times. Boston won the first eight NBA Finals series of the rivalry, spanning 3 decades – the 1950s, 1960s and 1980s – before the Lakers finally defeated Boston for the title in 1985 and again in 1987. Boston again topped the Lakers in 2008, but the Lakers gained revenge in 2010. This was the only Celtics/Lakers NBA Finals series that took place while the Lakers were based in Minneapolis, Minnesota. They remained in Minneapolis one more year before moving to their current home of Los Angeles, California.
