The 2003 NBA playoffs was the postseason tournament of the National Basketball Association's 2002–03 season. The tournament concluded with the Western Conference champion San Antonio Spurs defeating the Eastern Conference champion New Jersey Nets, 4 games to 2, in the NBA Finals. Tim Duncan was named NBA Finals MVP for the second time.
The 2003 Playoffs were notable for several reasons.
Despite relocating to New Orleans in the offseason, the Hornets made their third consecutive postseason. After Charlotte reclaimed the Hornets name and pre-2002–03 history in 2014 (and the Pelicans claimed the Hornets' history from 2002–03 onwards), this marked the first postseason for the New Orleans franchise.
The Portland Trail Blazers and Utah Jazz continued the longest active Western Conference playoff appearance streaks at the time, entering their 21st and 20th postseason appearances, respectively.
The Minnesota Timberwolves entered their seventh consecutive postseason. In addition, they were awarded home-court advantage for the first time in franchise history in their series against the Los Angeles Lakers.
The Orlando Magic became the seventh team to lose a playoff series despite leading 3–1, losing to the Detroit Pistons in the first round. The Magic would not win another playoff game again until 2008.
Game 5 of the Kings–Jazz series was the final game featuring Karl Malone and John Stockton as members of the Utah Jazz. Stockton would retire after the season while Malone would sign with the Lakers in the offseason. After this, the Jazz would not return to the playoffs until 2007.
With their first-round series loss to the Los Angeles Lakers, the Minnesota Timberwolves earned the dubious distinction of making their first seven postseason appearances, only to lose in the first round. They would break that streak by winning their first playoff series the following postseason.
The Portland Trail Blazers snapped a ten-game playoff losing streak dating back to 2000 with a Game 4 win in their first-round series against the Dallas Mavericks. The Trail Blazers also became the third team in NBA History to force a Game 7 after trailing 0–3 before bowing out. They would not return to the playoffs until 2009.
With their conference semifinals loss to the New Jersey Nets, the Boston Celtics were swept in a postseason series for the first time since 1983, and would not return to the Conference Semifinals until 2008.
With their conference semifinals loss to the San Antonio Spurs, the Lakers' championship streak was snapped at 3. With the win, the Spurs returned to the Western Conference Finals for the third time in five seasons.
With their conference semifinals win over the Philadelphia 76ers, the Detroit Pistons advanced to the Eastern Conference Finals for the first time since the Isiah Thomas and Joe Dumars-led team was swept by the Chicago Bulls in 1991. The Pistons would go on to appear in six consecutive Eastern Conference Finals through 2008, the most consecutive appearances for any Eastern Conference team since the Bill Russell-led Boston Celtics (1956–69).
With their conference semifinals victory over the Sacramento Kings, the Dallas Mavericks made the conference finals for the first time since 1988.
This was the first Western Conference Finals since 1995 to take place entirely in the state of Texas.
With their Eastern Conference Finals sweep of the Detroit Pistons, the New Jersey Nets won ten straight postseason games, the most since the 2001 Los Angeles Lakers.
In Game 6 of the Spurs–Mavericks series, Steve Kerr and Manu Ginóbili sparked a 42–15 run to help the Spurs advance to the NBA Finals for the first time since 1999. The Mavericks would not return to the Conference Finals (let alone face the Spurs in the playoffs) until 2006.
As of 2023, the 49–win New Jersey Nets are the most recent NBA Finals participant to win fewer than 50 games in an 82–game season. Four teams have since made the Finals with sub-50 win records, but each of those times, the season was shorter than 82 games for particular reasons:
