The ECW World Tag Team Championship was a professional wrestling world tag team championship contested for in Extreme Championship Wrestling (ECW). Originally, ECW was known as Eastern Championship Wrestling when it was a member of the National Wrestling Alliance (NWA), an organization that had numerous member promotions. ECW withdrew as a member of the NWA in 1994 and renamed itself to Extreme Championship Wrestling. The championship remained active until April 2001, when ECW filed for bankruptcy. All of ECW's assets were later purchased by World Wrestling Entertainment (WWE) in mid-2003, including the copyrights to ECW's championships.
