Melvin Guillard (born March 30, 1983) is an American mixed martial artist who competes in the Middleweight division.

He debuted in the company on The Ultimate Fighter 2 television series, losing to Josh Burkman by decision in the first Welterweight elimination bout.

Born and raised in Louisiana, Guillard competed in various sports such as basketball before he began wrestling at Bonnabel High School.

Guillard continued competing for one year at Colby Community College in Kansas and graduated with a degree in criminal law.

[4] Guillard had originally become drawn to mixed martial arts due to his wrestling coach's connections with the sport, and had the goal of fighting professionally by his early teens.

Guillard participated in The Ultimate Fighter 2, but was eliminated from the competition after losing a unanimous decision to Josh Burkman.

At UFC 63 on September 23, 2006, Guillard fought former WEC lightweight champion Gabe Ruediger and won the fight via KO by a body blow.

Guillard gave Clementi the finger during the introductions and attempted to attack him after the fight, but was restrained by referee Herb Dean.

[6] He was slated to fight Spencer Fisher at UFC 90, but tore his ACL while training and was replaced by Shannon Gugerty.

[14] However, headliner Kenny Florian pulled out of his fight with Evan Dunham due to injury and Guillard replaced him.

[18] Guillard was quickly submitted with a rear naked choke after being stunned by a counter left hook from Lauzon.

[29] The fight ended in a no contest when Pearson was deemed unable to continue after being cut on the forehead by an accidental illegal knee.

[33] On April 7, 2014, World Series of Fighting executive vice president Ali Abdel-Aziz confirmed Guillard had signed a multi-fight contract.

His manager, Malki Kawa, announced the news on Twitter: "I just received what I asked for from WSOF which is the release for [Melvin]... Should have a new home for him shortly".

"[39] In his debut fight for the promotion, Guillard was given the chance to face a hand picked opponent and chose Brandon Girtz, who he fought at Bellator 141 on August 28, 2015.

Guillard earned his first win in Bellator via a series of elbows and punches to defeat Rickels via KO in the first round.

[46] After the lone bout in Rizin, Guillard faced Terry House Jr. at United Combat League 32 on October 18, 2019.

[49][50] At BKB 6 on July 1, 2017 Guillard faced the "Undisputed King of Bare Knuckle" and its #1 star, Jimmy "Celtic Warrior" Sweeney.

[54][55] After the four-fight stint in BKB, Guillard made his promotional debut in BKFC against Isaac Vallie-Flagg at Bare Knuckle FC 7 on August 10, 2019.

[56] He lost the fight via technical knockout due to a hand injury that rendered him unable to continue after the third round.

[59] He lost the fight via disqualification in the second round due to an illegal blow that was ruled an intentional foul.

[62] On January 27, 2020, The Association of Boxing Commissions issued a news release concerning Guillard's expected fight at the BKFC: Knucklemania 2 event to take place on Feb 19 2020.

[65] Melvin attributed his drug abuse to the death of his father at age 44, from cirrhosis after a life of heavy drinking.

However, after Hurricane Katrina, his dad (a contractor) was backed up with work and so didn't make it to Guillard's UFC debut.

[67] In September 2018, news surfaced that Guillard was facing four felony charges stemming from two separate incidents: domestic violence against his girlfriend and an assault at a Denver bar.
