The 1978 NBA World Championship Series was the championship round of the National Basketball Association (NBA)'s 1977–78 season, and the culmination of the season's playoffs. The series featured the Western Conference champion Seattle SuperSonics against the Eastern Conference champion Washington Bullets. The Bullets defeated the SuperSonics in seven games to win their first NBA championship. Bullets power forward/center Wes Unseld was named MVP of the series. Before the Cleveland Cavaliers' Game 7 win at Golden State in the 2016 NBA Finals, this was the last time a road team had won Game 7 in the NBA Finals. The 1978 World Championship Series was the first NBA Finals series since the 1958 World Championship Series in which both teams had under 50 wins, and is the only NBA Finals to feature two teams with under 50 wins in an 82-game season. Background Seattle SuperSonics The Seattle SuperSonics had a disappointing start to the season, going 5–17 to begin with. Bob Hopkins, who replaced former Boston Celtics center Bill Russell as coach, was fired and Lenny Wilkens returned for a second tour of duty.

With Wilkens' experience being a key factor, the Sonics turned their season around, finishing with 47 wins and the fourth seed in the West. In the playoffs, they defeated the Los Angeles Lakers in a three-game miniseries, then upset the top-seeded and defending champion Portland Trail Blazers (who lost center Bill Walton in the second game of the series) in six games, before a six-game win over the Denver Nuggets in the Conference Finals sent them to their first of back-to-back NBA Finals appearances. Washington Bullets The Washington Bullets franchise made the Finals twice before in the 1970s, but were swept on both occasions, first by the Milwaukee Bucks in when they were still in Baltimore, and then by the Cinderella Golden State Warriors in . The Bullets kept some of the personnel from that 1975 team, including All-Stars Wes Unseld and Elvin Hayes, but Dick Motta was now in his second year of coaching duty. The Bullets struggled with injuries during the season, but managed to finish with 44 wins, good for the third seed in the East. In the playoffs, the Bullets disposed the Atlanta Hawks in a two-game first round series, then
