Gary "Big Daddy" Goodridge (born January 17, 1966) is a professional Super Heavyweight kickboxer and mixed martial artist of Trinidad and Tobago descent, now living and fighting out of Barrie, Ontario, Canada. Goodridge is known for his hard-hitting fighting style and showmanship. Besides martial arts, he is also renowned as one of the top ranked contenders in the world of professional arm wrestling.

Before Goodridge got into MMA he was a successful world champion at arm wrestling. He was able to defeat the likes of greats Sharon Remez and legendary John Brzenk in 1991.

Goodridge made an immediate impression on MMA competition, winning his first two fights in UFC 8 to reach the final against Don Frye. His first fight, against Paul Herrera, is considered one of the most brutal knockouts in UFC history - After Herrera attempted a fireman's carry, Goodridge trapped both of his arms in a crucifix hold and proceeded to deliver multiple elbow blows to the head, ending the bout in 13 seconds. He had knocked Herrera out after his second elbow thrown and proceeded to drop multiple more elbow strikes to Herrera's skull as Herrera lay flaccid and unconscious.

He lost his next fight against Frye, but returned again for UFC 9 and UFC 10. After his second loss to Don Frye in 1996, Goodridge moved from UFC to PRIDE. He retired from PRIDE competition due to alleged personal issues, and signed with K-1, and their MMA afiliate HERO'S, where he still competes today. He is also a trainer of up and coming fighter Mike Rowbotham

Big Daddy made his kickboxing debut in 1999 at K-1 Revenge, against Musashi and lost the fight by disqualification. His first win in K-1 came against Mike Bernardo by TKO in K-1 World GP 2002 in Las Vegas.

In 2005, Goodridge participated in two K-1 World GP tournaments held in United States. On April 30 in Las Vegas he knocked out Sean O'Haire and Scott Lighty and reached the finals, where he was stopped by Glaube Feitosa with a high kick KO. Three months later, on July 30, 2005, in Honolulu, Hawaii he scored three KO wins in three bouts to win the K-1 World Grand Prix in Hawaii Tournament.
