The 2002 NBA playoffs were the postseason tournament of the National Basketball Association's 2001–02 season. This was the final postseason that held a best-of-5 first-round series; the 2003 NBA playoffs saw those series expand to a best-of-7 format. The tournament concluded with the Western Conference champion Los Angeles Lakers defeating the Eastern Conference champion New Jersey Nets 4 games to 0 in the 2002 NBA Finals. Shaquille O'Neal was named NBA Finals MVP for the third straight year.

The 2002 playoffs are best remembered for that year's Western Conference Finals between the two-time defending champion Los Angeles Lakers and the Sacramento Kings. The matchup between the Lakers and Kings is regarded as one of the most controversial playoff series in NBA history. At the time, there was widespread criticism of the officiating as favoring the Lakers, especially in Game 6. Several years later, disgraced referee Tim Donaghy accused the Game 6 officiating crew of fixing the game, at the behest of the NBA's front office.

The 2002 NBA Playoffs marked the return of the Boston Celtics, who had last made the playoffs in 1995. In addition, the New Jersey Nets returned to the playoffs for the first time since 1998.

This also marked the last appearance of the Charlotte Hornets in the playoffs until 2010. The Hornets moved the next year to New Orleans, while an expansion team, formerly the Bobcats, was formed in 2004. The Hornets were renamed the Pelicans in 2013, after which the Bobcats reclaimed the Hornets name in 2014. The Hornets also reclaimed the history and records of the 1988–2002 Charlotte teams. This was also the most recent season in which the Hornets won a playoff series; since returning in 2004, the Hornets/Bobcats franchise only won a combined three playoff games, all in 2016, and failed to win a single game under the Bobcats branding.

The New York Knicks missed the playoffs for the first time since 1987, while the Miami Heat missed the playoffs for the first time since 1995. With that, Pat Riley missed the playoffs for the first time in his coaching career. Also the Phoenix Suns missed the playoffs for the first time since 1988.

With their first round series win over the Philadelphia 76ers, the Boston Celtics won their first playoff series since 1992.

With their first round series win over the Toronto Raptors, the Detroit Pistons won their first playoff series since 1991.

With their first round series win over the Indiana Pacers, the New Jersey Nets won a playoff series for the first time since 1984.
