A ball holder for a table tennis table designed for non-intrusive mounting under a corner of a table tennis table. The ball holder can be manufactured in two parts for ease of sale and construction, with the two halves being easily assembled and secured by the user. The two halves can connect using a set of male and female tabs, and secure using a set of bolts. The full assembly can attach to the table tennis table through the use of four screws. Properly assembled, the ball holder can contain multiple table tennis balls in an easily accessible position, but without obstructing the players' range of motion or creating a hazard.
