The 1983 NBA World Championship Series was the championship round of the 1982–83 NBA season.

The final piece of the Philadelphia 76ers' championship puzzle was completed before the 1982-83 season when they acquired center Moses Malone from the Houston Rockets. They went on to capture their historic second NBA championship as they won 65 games, and stormed through the playoffs, first sweeping the New York Knicks, and then beating the Milwaukee Bucks in five games. They finally finished it off with a four game sweep of the Los Angeles Lakers, who had defeated them the season before.

Said head coach Billy Cunningham, "The difference from last year was Moses." Malone was named MVP of the 1983 Finals, as well as league MVP for the third time in his career. The 76ers completed one of the most dominating playoff runs in league history with a 12-1 mark after league and NBA Finals MVP Moses promised "Fo', fo', fo" (as in "four, four, four" - four wins to sweep round 1, four wins to sweep round 2, etc.), but it actually wound up as "Fo', fi', fo." (four, five, four). The 76ers were also led by Julius Erving, Maurice Cheeks, Andrew Toney, and Bobby Jones.

The NBA Finals is the championship series of the NBA. The series was named the NBA World Championship Series until 1986.

The series is played between the winners of Western Conference Finals and Eastern Conference Finals. At the conclusion of the championship round, the winners of the NBA Finals are awarded the Larry O'Brien Championship Trophy. (Winners from 1946 to 1977 received the Walter A. Brown Trophy) The NBA Finals has been played at the conclusion of every NBA and BAA season in history, the first being held in 1947.

Since 1985, the winner of the NBA Finals has been determined through a 2–3–2 format. The first two and the last two games of the series are played at the arena of the team who earned home court advantage by having the better record during the regular season.

During the first decade the Minneapolis Lakers had the first NBA dynasty, winning 5 championships in 6 years under Hall of Fame head coach John Kundla. The team also featured George Mikan, one of the greatest players in the history of the NBA. Franchises which had previously been in the National Basketball League tended to dominate, especially the Minneapolis Lakers.

Earvin "Magic" Johnson Jr. (born August 14, 1959) is a retired American professional basketball player who played point guard for the Los Angeles Lakers of the National Basketball Association (NBA). After winning championships in high school and college, Johnson was selected first overall in the 1979 NBA Draft by the Lakers. He won a championship and an NBA Finals Most Valuable Player Award in his rookie season, and won four more championships with the Lakers during the 1980s. Johnson retired abruptly in 1991 after announcing that he had contracted HIV, but returned to play in the 1992 All-Star Game, winning the All-Star MVP Award. After protests from his fellow players, he retired again for four years, but returned in 1996, at age 36, to play 32 games for the Lakers before retiring for the third and final time.

Johnson's career achievements include three NBA MVP Awards, nine NBA Finals appearances, twelve All-Star games, and ten All-NBA First and Second Team nominations. He led the league in regular-season assists four times, and is the NBA's all-time leader in average assists per game, at 11.2. Johnson was a member of the "Dream Team", the U.S. basketball team that won the Olympic gold medal in 1992.

Julius Winfield Erving II (born February 22, 1950), commonly known by the nickname Dr. J, is a retired American basketball player who helped launch a modern style of play that emphasizes leaping and play above the rim. Erving helped legitimize the American Basketball Association (ABA). He was the best known player in the ABA when the ABA-NBA merger joined it with the National Basketball Association (NBA) after the 1976 season.

Erving won three championships, four Most Valuable Player Awards, and three scoring titles while playing with the ABA's Virginia Squires and New York Nets, and the NBA's Philadelphia 76ers. He is the fifth-highest scorer in professional basketball history, with 30,026 points (NBA and ABA combined). He was well known for slam dunking from the free throw line in Slam Dunk Contests and was the only player to have been voted Most Valuable Player in both the ABA and the NBA.

Erving was named to the NBA's 50th Anniversary All-Time team and in 1993 was inducted into the Basketball Hall of Fame. In 2004, he was inducted into the Nassau County Sports Hall of Fame. Many consider him among the most spectacular basketballers ever, and one of the best dunkers of all time. While players such as Connie Hawkins, "Jumping" Johnny Green, Elgin Baylor, and Gus Johnson were performing spectacular dunks before Erving's time, "Dr. J" is usually the one most people credit with bringing the practice into the mainstream. His signature dunk was the "slam" dunk, since incorporated into the vernacular and basic skill set of the game, in the same manner as the "cross-over" dribble and the "no look" pass.
