The 1974 NBA playoffs was the postseason tournament of the National Basketball Association's 1973-74 season. The tournament concluded with the Eastern Conference champion Boston Celtics defeating the Western Conference champion Milwaukee Bucks 4 games to 3 in the NBA Finals. John Havlicek was named NBA Finals MVP.
It was the Celtics' twelfth NBA title, and first accomplished in the post-Bill Russell era. It was the last Finals appearance for Milwaukee until 2021.
This is the last postseason with only 3 rounds and using only 8 teams. The 1975 NBA Playoffs added a First Round and the number of teams was expanded to 10.
Using the revised playoff format adopted in 1973, two third-place teams (Buffalo in the Atlantic Division, Detroit in the Midwest Division) qualified for the playoffs, while the second-place finishers in the Central (Atlanta) and Pacific (Golden State) divisions did not. Also, since the top three Western qualifiers were in the Midwest Division, the two divisional champions in the Western Conference (Milwaukee and Los Angeles) played in the conference semifinals.
With a 4–3 series victory over the Pistons in the first round, the Bulls earned their first playoff series victory. In their first eight years of existence, the Bulls made the playoffs seven times.
As a matter of historical curiosity, 3 of the 4 teams in the 1974 Western Conference bracket (Milwaukee, Detroit and Chicago) now reside in the Eastern Conference.
This was the only appearance of the Capital Bullets in the playoffs under that moniker; they assumed the "Capital" name for one year before changing to the Washington Bullets the next season. It was the playoff debut of the Buffalo Braves, who had joined the league in 1970.
For the first time in BAA/NBA history (dating back to 1947), neither the Lakers (of Minnesota, then Los Angeles) or Warriors (of Philadelphia, then San Francisco and Golden State) participated in a conference (or division prior to 1971) finals series.
