Jay Dee "B.J." Penn III (born December 13, 1978) is an American former professional mixed martial arts (MMA) fighter. He is also a 5th-degree black belt in Brazilian Jiu-Jitsu (BJJ). Penn is a famous figure in the Ultimate Fighting Championship (UFC). He was both a UFC Lightweight Champion and a UFC Welterweight Champion. He is only the second fighter in UFC history to win titles in two different weight classes.

Before his MMA career, Penn became the first non-Brazilian to win the World Jiu-Jitsu Championship at the black belt level. This amazing achievement earned him the nickname "The Prodigy." In MMA, he competed in many weight classes, from Featherweight to Heavyweight. In 2015, Penn was honored by being one of the first people added to the Modern-era wing of the UFC Hall of Fame.

Many people think Penn was one of the best fighters in the world during his career. UFC President Dana White said Penn helped make the lighter weight classes popular. White called him a "crossover pay-per-view star" who helped build the 155-pound division.

Early Life and Martial Arts Training

Penn was born in Kailua, Hawaii. His father, Jay Dee Penn, is of Irish American descent, and his mother, Lorraine Shin, is of Korean and Hawaiian descent.

When he was 17, Penn started training in Brazilian Jiu-Jitsu. His neighbor, Tom Callos, introduced him to the sport. Soon after, Penn moved to California to train at the Ralph Gracie BJJ academy. This is where he decided to make martial arts his career.

Mixed Martial Arts Career

A Champion in Brazilian Jiu-Jitsu

Penn started training in BJJ in 1997. He earned his black belt in 2000, which is a very fast progression. Just a few weeks later, he won the black-belt division of the World Jiu-Jitsu Championship in Brazil. He was the first person not from Brazil to ever win this title. This incredible accomplishment is why he is called "The Prodigy."

Joining the Ultimate Fighting Championship

Penn's success in BJJ got the attention of the UFC. He made his MMA debut on May 24, 2001, at UFC 31 and won. He quickly showed powerful striking skills. After a championship fight against Jens Pulver ended in a loss, the UFC temporarily suspended the lightweight division.

In 2004, Penn moved up to the welterweight division to challenge the champion, Matt Hughes, at UFC 46. Even though Hughes was expected to win, Penn won the fight in the first round with a rear naked choke. This victory made him the UFC Welterweight Champion and is considered one of the biggest upsets in MMA history.

Fighting in Japan and Returning to the UFC

For a short time, Penn fought for the K-1 promotion in Japan. He won two fights there before returning to the UFC in 2006. His first fight back was against Georges St-Pierre, which he lost by a close split decision.

Later that year, he had a rematch with Matt Hughes for the welterweight title. Penn controlled the first two rounds but injured his rib. He became tired in the third round, and Hughes won the fight by TKO.

Penn then became a coach on the TV show The Ultimate Fighter 5. He coached a team of lightweight fighters against a team coached by Jens Pulver. At the end of the season, Penn defeated Pulver by submission.

Winning the Lightweight Championship

On January 19, 2008, Penn fought Joe Stevenson for the vacant UFC Lightweight Championship at UFC 80. Penn dominated the fight from the start. He won in the second round with a rear-naked choke, becoming the new champion. This made him the second fighter ever to win UFC titles in two different weight classes.

Penn defended his title against former champion Sean Sherk at UFC 84. Penn won by TKO at the end of the third round. After the fight, he asked the crowd if they wanted to see him fight Georges St-Pierre again, and they cheered loudly.

Challenging for the Welterweight Title

Penn challenged Georges St-Pierre for the welterweight title on January 31, 2009, at UFC 94. The first round was even, but St-Pierre controlled the rest of the fight. After the fourth round, Penn's corner stopped the fight.

There was some controversy after the fight. St-Pierre's corner was seen rubbing Vaseline on his back, which is not allowed. This became known as "Greasegate." The athletic commission investigated but found no wrongdoing. However, the UFC changed its rules to prevent this from happening again.

Defending the Lightweight Title

Penn returned to the lightweight division to defend his title. He defeated Kenny Florian at UFC 101 by submission in the fourth round. This was his first successful title defense.

His next defense was against Diego Sanchez at UFC 107. Penn controlled the entire fight and won by TKO in the fifth round. This victory set a new record for the most title defenses in the UFC lightweight division (three).

Losing the Title

At UFC 112 in April 2010, Penn fought Frankie Edgar. In a surprising result, Penn lost a very close fight by unanimous decision. Many people thought Penn had won, so an immediate rematch was scheduled.

In the rematch at UFC 118, Edgar won again, this time more clearly. All three judges scored the fight for Edgar.

Later Career and Retirement

After losing the title, Penn moved back to welterweight. He fought Matt Hughes for a third time at UFC 123. Penn won by knockout in just 21 seconds.

Penn then fought top contender Jon Fitch to a draw. His next fight was against Nick Diaz at UFC 137. Penn lost by unanimous decision. After the fight, he announced he was thinking about retiring.

He returned in 2012 to fight Rory MacDonald but lost the fight. In 2013, it was announced that Penn would coach The Ultimate Fighter against Frankie Edgar for a second time. They fought for a third time at the end of the season, with Penn moving to the featherweight division. Edgar won the fight by TKO, and Penn announced his retirement again.

After a break, Penn returned to fighting in 2017. He fought four more times but lost each match. His final fight was against Clay Guida on May 11, 2019, at UFC 237.

Personal Life

His nickname "B.J." is short for "Baby Jay." He is the youngest of three brothers all named "Jay Dee Penn."

Penn is proud of his Hawaiian heritage and often uses Hawaiian music for his walk-out entrances. He is the co-author of an instructional book on MMA and an autobiography called Why I Fight: The Belt is Just an Accessory.

In 2021, Penn announced he would run for governor of Hawaii. He did not win the Republican primary election. In 2024, he ran for a seat on the Hawaii County Council.

Legacy and Influence

Penn is seen as one of the biggest stars in MMA history. He helped make the lightweight division popular at a time when the UFC was thinking about getting rid of it. His nickname, The Prodigy, came from how quickly he earned a black belt in BJJ and won a world championship.

In May 2015, the UFC announced that Penn would be inducted into the UFC Hall of Fame. Many other famous fighters, like Anderson Silva and Mark Coleman, have called Penn one of the greatest fighters of all time.
