As of September 2021, there is no official list of fastest 40-yard dash times specifically for NBA players. The 40-yard dash is primarily used as a measurement in American football scouting combines and not commonly tracked in basketball. Therefore, it is difficult to provide an accurate list of the top ten fastest times for current NBA players.
The fastest 40 yard dash time is 4.22 seconds, achieved by John Ross at the NFL Scouting Combine in 2017.
