The 1992–93 NBA season was the 47th season of the National Basketball Association. The season ended with the Chicago Bulls winning their third-straight NBA Championship, beating the Phoenix Suns 4 games to 2 in the NBA Finals.
* The Charlotte Hornets became the first of the four late-1980s expansion franchises to win a playoff series on Alonzo Mourning's 20-foot jumper at the buzzer in Game 4 of their first round playoff series against the Boston Celtics.
* Michael Jordan scored his 20,000th career point and tied Wilt Chamberlain's record of seven scoring titles.
* In Game 3 of the NBA Finals, the Suns defeated the Bulls in triple overtime, 129–121. This marked the second time a Finals game lasted three overtimes, along with Game 5 of the 1976 Finals, which also involved the Suns. Coincidentally, in the 1976 game, Paul Westphal played for the Suns, and in the 1993 game, he coached the Suns.
* Michael Jordan scored 40 or more points in 4 consecutive games of the NBA Finals, setting a record, and averaged an NBA Finals record 41.0 points per game for the series.
* The Chicago Bulls defeated the Phoenix Suns in the NBA Finals to become the first team in almost 30 years to win three consecutive championships.
* New Jersey Nets guard Dražen Petrović was killed in an automobile accident in Munich, Germany on June 7. Almost two months later, on July 27, Boston Celtics guard Reggie Lewis collapsed during practice and died of a heart condition later the same day. Both were later honored by their respective teams by retiring their numbers, and Petrovic would be eventually inducted into the Basketball Hall of Fame.
* The Dallas Mavericks became the third team to lose 70 games in a season, after the 1972–73 Philadelphia 76ers and the 1986–87 Los Angeles Clippers, they finished 11–71. They would later be joined by the 1997–98 Denver Nuggets, the 2009–10 New Jersey Nets and the 2015-16 Philadelphia 76ers.
* During the regular season, there were three instances where games had to be stopped due to damage to the goals.
* On February 7 in the game between the Orlando Magic and the Phoenix Suns at America West Arena, Magic rookie Shaquille O'Neal went up for a dunk and the recoil due to his massive size was too much for the stanchion to bear; the supports detached and the basket folded in on itself.
* On March 12, during a game between the Chicago Bulls and New Jersey Nets at Brendan Byrne Arena that was televised nationally on TNT, Nets forward Chris Morris shattered the glass behind the rim with a forceful dunk.
* On April 23, in another game played in New Jersey between the Nets and Magic, O'Neal struck again; this time, he dunked with so much force that the entire backboard, including the shot clock positioned above it, was pulled off the goal. This led the league to provide stronger shatterproof backboards. However, every team is still required to have a spare backboard in their home arenas just in case.
