The most blocks by a team in an NBA game is 23, achieved by the Toronto Raptors on March 23, 2001, in a 112-86 win over the Hawks. Center/forward Keon Clark led Toronto with 12 rejections — tied with JaVale McGee (2011) and Hassan Whiteside (2015) for the most by one player in a single game since 2000 — followed by Vince Carter, with four swats, and five other Raptors who recorded at least one.

With 23 blocks, Toronto surpassed the Nets’ mark of 22 (set in 1991) for the NBA record and became just the fifth team in league history to eclipse 20 rejections in a single game since blocks were first fully recorded in 1973-74.
