The Unholy Alliance was the tag team of Mikey Whipwreck and Yoshihiro Tajiri in Extreme Championship Wrestling (ECW).
On August 24, 2000, at Midtown Massacre, Whipwreck and Tajiri won a one-night tournament to be crowned new ECW World Tag Team Champions (Justin Credible "dropped" the belts so he could face Tommy Dreamer for the ECW Title) when they defeated Tommy Dreamer and Jerry Lynn and Simon Diamond and Johnny Swinger in a 3-way match in the finals.

The Unholy Alliance reunited at ECW One Night Stand on June 12, 2005, when Whipwreck and the Sinister Minister managed Tajiri during his match with Super Crazy and Little Guido.
