The San Antonio Spurs of the Western Conference took on the New Jersey Nets of the Eastern Conference for the title, with the Spurs holding home-court advantage. The series was played under a best-of-seven format. The Spurs won the series 4 games to 2 to win their second NBA championship.
The series was broadcast on U.S. television on ABC, with Brad Nessler, Bill Walton, and Tom Tolbert announcing.
The 2003 Finals documentary was narrated by Rodd Houston, who later narrated three other NBA Finals series.
This was the first NBA Finals since 1995 to use the traditional script font in its logo; in the intervening years, a more contemporary all-gold logo had been used with the Larry O'Brien Trophy, as well as the year and the series' name encompassed by an oval on a black background.
The Nets were the first team since the Utah Jazz in 1997 and 1998 and the last until the Cleveland Cavaliers in 2017 and 2018 to lose the Finals two years in a row having being swept by the two-time defending champion Los Angeles Lakers in the previous year's Finals.
As of 2021, this was the last time that the Nets made it to the NBA Finals.
