Barry Buchanan (born January 15, 1968) is a professional wrestler, best known for playing the character Bull Buchanan in the World Wrestling Federation (now World Wrestling Entertainment).

The first major wrestling organization that Buchanan competed for was the United States Wrestling Association, where he was known as Recon of the Truth Commission. With his partner The Interrogator, Buchanan won the USWA Tag Team Championship. The entire Truth Commission faction was brought in to the World Wrestling Federation in 1997 but did not remain in the company for long. Buchanan remained under WWF contract, however, and was sent to their "developmental territory" Ohio Valley Wrestling to improve his skills. While there, Buchanan and partner Mr. Black captured the OVW Tag Team Title.

Buchanan returned to the WWF in 2000, now under the name Bull Buchanan and acting as a tag team partner for the Big Boss Man (Ray Traylor). Buchanan briefly struck out on his own after that alliance ended, but it was not long before he joined the Right to Censor, lead by Steven Richards. As part of this group, Buchanan won the WWF Tag Team Title with the Goodfather.

When the Right to Censor was disbanded, Buchanan was once again sent to Ohio Valley Wrestling. In 2002 he returned to WWF (now WWE). After wrestling several matches with seemingly no character or purpose, Buchanan was teamed with John Cena and began using the name B-2 (also written as B²) (pronounced "B-Squared"). This pairing did not last long, as Buchanan was released by the company. Since that time, Buchanan has been wrestling for All Japan Pro Wrestling, where he is known simply as Buchanan.
