Logan Paul is now a wrestling champion, 'cause the dude just won a major WWE event in Saudi Arabian ... which saw him raise a gold belt in glory.
The YouTuber-turned-athlete competed Saturday in WWE's Crown Jewel over in Riyadh -- and his match against Rey Mysterio was the main event ... one that he ultimately emerged victorious from after taking a pummeling in the ring.
There was a lot of back and forth between and RM ... and a lot of body slams. In the end, Logan won by "punching" Rey after he jumped toward him from the ropes -- which knocked Rey out cold.
