what is the undertakers real name

I am a huge fan of the 16-0 man.His real name is Mark Calaway.I hope this helped.

Mark Calaway ... born March 24, 1965 in Houston, Texas ... formerly know as: The Master of Pain, The Punisher, Mean Mark ... member of The New Skyscrapers.
The only superstar who can walk the top rope perfectly (tought to him by Don 'The Spoiler' Jardine)
My only regret is that I live to far away to see 'The Phenom' live in action and that there's no chance to ever meet him personally.
Good luck 'Deadman' in Wrestlemania 25 (don't think you'll need it) to keep your winning streak.
