Clayton Charles Guida (; born December 8, 1981) is an American professional mixed martial artist, currently signed to the UFC competing in the Lightweight division. A professional competitor since 2003, Guida also formerly competed for Strikeforce, the WEC, King of the Cage, and Shooto. Guida was the inaugural Strikeforce Lightweight Champion.

Background
Born and raised in Illinois into an Italian family, Guida began wrestling at the age of five and was a three-sport athlete at Johnsburg High School. He continued his wrestling career for Harper College, where he competed at 149 lbs. He is the younger brother of fellow mixed martial artist, Jason Guida.

Mixed martial arts career

Early career
Guida made his professional debut in the summer of 2003, losing via rear-naked choke in the first round. After compiling a record of 3-3, he then won his next 15 consecutive fights before losing via submission at a King of the Cage event in February 2006. Guida was then signed by Strikeforce and fought a month later against Josh Thomson for the Strikeforce Lightweight Championship. Guida won via unanimous decision, before losing to the then-undefeated Gilbert Melendez. After losing his next bout overseas in Japan via submission, Guida was signed by Zuffa and the WEC, making his promotional debut at WEC 23. He won via unanimous decision. With an overall record of 20-6, Guida was signed by the UFC.
