Chyna (born Joan Marie Laurer; December 27, 1969 – ≈ April 20, 2016) was an American professional wrestler, glamour model, pornographic film actress, and bodybuilder.

Chyna first rose to prominence in the professional wrestling promotion the World Wrestling Federation in 1997, where she was billed as the "Ninth Wonder of the World" (André the Giant was already billed as the eighth). A founding member of the stable D-Generation X as the promotion's first female enforcer, she held the WWF Intercontinental Championship (the only female performer to do so) twice and the WWF Women's Championship once. She was also the first woman to participate in the Royal Rumble and King of the Ring events, as well as to become number one contender to the WWF Championship. With singles victories over several prominent male wrestlers – including multiple-time world champions Triple H, Kurt Angle, Chris Jericho and Jeff Jarrett – Chyna left what WWE (formerly WWF) called "a lasting legacy as the most dominant female competitor of all time". After leaving the WWF in 2001, Chyna wrestled sporadically, with New Japan Pro Wrestling in 2002 and Total Nonstop Action Wrestling in 2011.
