1984–85 NBA season

The 1984–85 NBA season was the 39th season of the National Basketball Association. The season ended with the Los Angeles Lakers winning the NBA Championship, beating the Boston Celtics 4 games to 2 in the NBA Finals. This was David Stern's first full season as commissioner.

Notable occurrences

 * The 1985 NBA All-Star Game was played at Hoosier Dome in Indianapolis, with the West defeating the East 140–129. Ralph Sampson of the Houston Rockets won the game's MVP award. Dominique Wilkins of the Atlanta Hawks won the Slam Dunk Contest.
 * Michael Jordan became the first rookie in NBA history to lead a team in four statistics (points, assists, rebounds, steals). No other rookie would do so until Victor Wembanyama led the 2023–24 San Antonio Spurs in points, rebounds, steals, and blocks.
 * The Clippers relocated from San Diego to Los Angeles. This created a situation with two teams of the same host name (the other Los Angeles team being the Lakers) in the same division, the Pacific, similar to the one in the NHL where the Patrick Division (at the time, and now the Metropolitan Division) had two teams of the same host name: the New York Islanders and Rangers. There was a similar scenario which only existed in the 1976–77 season, in which the Atlantic Division had the New York Knicks and the Nets, until the Nets moved to New Jersey the following season and changed their name.
 * Turner Broadcasting began a relationship with the NBA that continues today when TBS signed a two-year, $20 million deal with the NBA.
 * The Kings played their final game in Kansas City, Missouri, and moved their franchise to Sacramento the following season.
 * Knicks forward Bernard King, who finished the season as the scoring champion, ruptured his ACL in his right knee in the Knicks' final game in Kansas City before the Kings' move to Sacramento. King was out of action for two whole seasons. He would come back in 1987–88, but would not return to the All-Star Game until 1990–91.
 * This season marked Michael Jordan's, Akeem Olajuwon's, Charles Barkley's and John Stockton's rookie seasons in the NBA.
 * This season saw the final season for Dan Issel, Billy Knight, M.L. Carr and Lionel Hollins.
 * Due to a roof collapse at the Pontiac Silverdome, the Pistons were forced to rent the Joe Louis Arena, home of the NHL's Detroit Red Wings, for the remainder of the season and into the playoffs. Both the Pistons and the Red Wings would move their home games to the Little Caesars Arena, starting in 2017.
 * At age 38, Kareem Abdul-Jabbar became the oldest player to win the honor of Finals MVP. Jabbar's team, the Lakers, became the first visiting team to win the NBA title at Boston Garden, beating their archrivals, the Boston Celtics, in six games.
 * The Finals adopted the 2–3–2 format which was used through the 2013 NBA Finals after which the league returned to the 2–2–1–1–1 format.
 * The Cleveland Cavaliers returned to the playoffs after a seven-year absence. They were eliminated by the Celtics in four games. They would not make the playoffs again until 1988. The Cavaliers were coached by George Karl, then making his NBA coaching debut.
 * At New Orleans' Lakefront Arena (where the Atlanta Hawks played 12 of 41 home games that season), Larry Bird scored a Celtics' franchise record 60 points in Boston's 126–115 victory over the Hawks on March 12. Bird broke the previous franchise record set by teammate Kevin McHale (56) nine days earlier at Boston Garden against the Pistons.
 * The Denver Nuggets made the conference finals for the first time since 1978, losing 4–1 to the Lakers. They would not make the conference finals again until 2009, which they lost to the Lakers again. The series marked the end of Dan Issel's playing career, having played 15 professional seasons and averaging 22.6 points and 9.1 rebounds in his career.
 * This was the last season of the backboard height set at 48 in. It would be shortened 6 in next season to the current 42 in. The NBA logo is added on the lower left hand corner of the backboard starting this season.
