The 1997–98 NBA season was the 52nd season of the National Basketball Association. The season ended with the Chicago Bulls winning their third straight championship and sixth in the last eight years, beating the Utah Jazz 4 games to 2 in the 1998 NBA Finals. It also marked the departure of Michael Jordan and the end of the dynasty for the Chicago Bulls.
* The Washington Bullets were renamed the "Wizards". They began the season at US Airways Arena, then in December, they played their first game at the MCI Center (later Verizon Center, now Capital One Arena) during this season.
* Due to the demolition of The Omni and the construction of the new Philips Arena, the Atlanta Hawks split home games between Georgia Tech's Alexander Coliseum (Their original home where they played for four seasons when they moved to Atlanta in 1968.) and the Georgia Dome.
* Golden State Warriors swingman Latrell Sprewell made headlines by choking Warriors head coach P. J. Carlesimo during practice on December 1, 1997. Sprewell was ultimately suspended for 68 games, at the time the longest in NBA history. Sprewell would be traded to the New York Knicks in the off-season that followed.
* Michael Jordan passed Kareem Abdul-Jabbar as the all-time leader in points scored in the NBA Playoffs.
* The Utah Jazz and the Chicago Bulls shared the league's best record at 62–20, and met each other in the NBA Finals. The Jazz had home-court advantage by virtue of the head-to-head match-up (the Jazz won the season series 2–0).
* Two new records were set in Game 3 of the NBA Finals: biggest margin of victory (42 points) and fewest points scored in an NBA Finals game (54) in the Bulls' rout of the Jazz.
* The San Antonio Spurs set a league record for the biggest single-season turnaround (36 wins), breaking their own record set in the 1989–90 NBA season; it was later broken by the 2007–08 Boston Celtics.
* Following head coach Phil Jackson's decision to not return to the Bulls, Michael Jordan announced his second retirement from the NBA during the following offseason. This was Jordan's final season with the Chicago Bulls. Scottie Pippen was traded for Roy Rogers (who was released in February 1999) and a conditional second-round draft pick from the Houston Rockets. Dennis Rodman was not re-signed either, leading to the end of an era for the Bulls and the NBA.
* Houston Rockets guard Clyde Drexler retired after fifteen seasons, twelve of which he spent with the Portland Trail Blazers, where he led the team to two NBA Finals, in 1990 and 1992. He won his only NBA championship in 1995 while playing for the Rockets.
* Dallas Mavericks forward A.C. Green breaks the NBA's Iron Man Streak of most consecutive games played, surpassing Randy Smith who played 906 consecutive games.
* The restricted area arc was allowed.
* On February 27, the Indiana Pacers defeated the Portland Trail Blazers 124–59, marking the first time in NBA history that one team scored more than twice as many points as its opponent.
* Nike became the official outfitter for select NBA teams (Boston Celtics, Chicago Bulls, Dallas Mavericks, Detroit Pistons, Los Angeles Lakers, Miami Heat, Portland Trail Blazers, San Antonio Spurs, Toronto Raptors and Washington Wizards), which ran for seven years. Other NBA teams were outfitted by Starter Clothing Line, Puma, Reebok or Champion.
* The Denver Nuggets lost 71 games, joining the 1972–73 Philadelphia 76ers, 1986–87 Los Angeles Clippers, and 1992–93 Dallas Mavericks (plus subsequently the 2009–10 Nets and 2015–16 76ers) as the only teams to lose 70 games in a season. The Nuggets also equaled the longest single-season losing streak with 23 consecutive losses, sharing the mark with the 1995–96 Vancouver Grizzlies.
* All the Western Conference teams who missed the playoffs had 55 or more losses. Four of them lost more than 62 games. The ninth-placed Sacramento Kings finished the season with a 27–55 record, losing nineteen of their last twenty games. The Kings finished fourteen games behind the #8 seeded Houston Rockets, who finished with a 41–41 record, whilst the tenth-placed Dallas Mavericks ended with a 20–62 record. All the Eastern Conference teams who missed the playoffs had 31 or more wins except for the Toronto Raptors, who finished with a 16–66 record.
* Violet Palmer and Dee Kantner became the first two female officials in NBA history (as well as any of the four major professional sports leagues). Kantner would be fired following the 2001–02 season, while Palmer would go on to have long 19-year career before retiring after the 2015–16 season.
