John Wall had one helluva Saturday night -- beating the Mavericks ... and then throwing a TON of cash at a Dallas strip club ... and TMZ Sports has the footage.

The Washington Wizards superstar hit up V Live in Dallas -- and we're told he went on a $47,000 tear ... showering the stage with fistfuls of cash.

Our sources tell us the dancers LOOOOVED Wall -- and say he's one of their all-time favorites at the club ... which is impressive considering it's frequented by huge stars like Drake and T.I.

In case you're wondering, Wall has made more than $50 million in his NBA career -- so, yeah ... he can afford it.
