Metta World Peace has a son who can ball -- 15-year-old Ron Artest III -- who was throwing down some ferocious dunks in his high school gym ... and it was all caught on tape.
Here's what we know ... RA3 is one of the stars of his high school basketball team in L.A. We're told the kid (a sophomore) is already 6'8" and is being recruited by several college programs.
Plus, our high school basketball sources tell us Ron can dunk from the free throw line!!
Clearly, Metta's impressed with his son's hops -- he tweeted, "Check out my 15 year old son jumping higher than his dad. This is really weird."
