The 1970 NBA expansion draft was the fifth expansion draft of the National Basketball Association (NBA). The draft was held on May 11, 1970, so that the newly founded Buffalo Braves, Cleveland Cavaliers, and Portland Trail Blazers could acquire players for the 1970–71 season. Buffalo, Cleveland, and Portland were awarded the expansion teams on February 6, 1970. Houston was also awarded a franchise, but the group backing the team was unable to come up with the US$750,000 down payment on the US$3.7 million entrance fee that was required before the 1970 NBA draft. The Braves later underwent two relocations, moving to San Diego in 1978 and changing their name from the Braves to the Clippers, and then relocating to Los Angeles in 1984. They are currently known as the Los Angeles Clippers.

The Buffalo Braves were an American professional basketball franchise based in Buffalo, New York. The Braves competed in the National Basketball Association (NBA) as a member club of the league's Eastern Conference Atlantic Division from 1970 until 1978. In 1978, Braves owner John Y. Brown Jr. swapped franchises with then-Boston Celtics owner Irv Levin, who then moved the team to San Diego, where it was renamed the San Diego Clippers. The franchise relocated to Los Angeles in 1984, becoming the Los Angeles Clippers.
