WWE Tough Enough (originally known as WWF Tough Enough) was a reality television show produced by World Wrestling Entertainment (WWE) and MTV wherein participants underwent professional wrestling training and competed for a contract with WWE. There were two winners per season for the first three seasons but only a single winner for the fourth season. All three televised seasons aired on MTV. A fourth competition was held in 2004, but was integrated into UPN's WWE SmackDown!

Currently (as of January 4, 2009), the only Tough Enough winner still wrestling for WWE is John Hennigan, wrestling as John Morrison on the ECW brand. He is the first Tough Enough contestant to win a major World Championship in WWE (though Tough Enough I winner Maven Huffman also held for a short period the WWF Hardcore Championship).

Together, John Morrison and The Miz are former WWE Tag Team Champions; both of whom are Tough Enough alumni.
