WWE legend Ric Flair is back wrestling ... the Hall of Famer just announced he'll be returning to the squared circle this summer for the last time in his storied career.
The 16-time World Heavyweight champion's opponent is not yet known.
It's been a while since we've seen "The Nature Boy" in action ... Ric's last match was against the icon Sting when he was still a member of TNA Impact.
In 2008, Flair officially retired from the WWE after the "Heartbreak Kid" Shawn Michaels defeated him in a match -- where his career was on the line -- at WrestleMania 24.
