The UFC is such a close-knit organization that has only a handful of fighters on their roster. These fighters are considered as the best martial artists in the world and they are also regarded as the few and the chosen.
But despite the UFC’s small world, there have been families who have sent more than one representative to the UFC. These siblings have at least fought once inside the UFC octagon to be included in our list.
Here is the list of the top siblings who fought for the UFC:
Frank and Ken Shamrock
The Shamrock brothers were among the UFC pioneers. You can’t talk about the UFC’s early days without mentioning them and their Lion’s Den team. Ken is the older brother and the more successful one. He headlined a total of 15 main events and co-main events during his career and was a former UFC Superfight champion. Ken is known as the World’s Most Dangerous Man and was also a successful professional wrestler with the WWF.
Frank was the first fighter to win the UFC middleweight championship and was the #1 pound for pound fighter during his reign as champion. The Fighter of the Decade for the 90s by Wrestling Observer also won championships in Pancrase, WEC, and Strikeforce. Frank is an adopted brother of Ken Shamrock and the two have hated each other after Ken threw a computer monitor at Frank.
Nate and Nick Diaz
The most popular fighters to come out of Stockton, California are the Diaz brothers and they have been in the fight scene for the last two decades. Nick was first in the octagon in 2003 but after going 4-4, he left in 2006. He became Strikeforce welterweight champion and defended the belt three times before rejoining the UFC. He earned back to back title shots but never won the UFC gold.
Nate won The Ultimate Fighter 5 lightweight tournament and is one of the most awarded fighters in the UFC with 15 post-fight bonuses, second-most in the history of the promotion. Nate didn’t accomplish as much as his big brother Nate but at UFC 202 in 2016, he and Conor McGregor set the UFC PPV record. Nate also fought Jorge Masvidal for the inaugural BMF belt at UFC 244.
Antonio Rodrigo and Antonio Rogerio Nogueira
The Nogueira twins are more popularly known as Big Nog and Little Nog. Minotauro or Big Nog is Rodrigo who is a former interim UFC heavyweight champion. Big Nog was the first PRIDE Heavyweight champion in Japan and is one of only three fighters in history to hold championships in PRIDE and the UFC. He defeated Tim Sylvia at UFC 81 to win interim UFC gold but lost the belt to Frank Mir in his next bout.
Minotouro or Little Nog was an accomplished boxer, winning the bronze medal at the 2007 Pan-American games. He also fought at PRIDE and Affliction before joining the UFC. Little Nog never found the same amount of success as Big Nog but he has notable wins over former MMA champions Alistair Overeem, Tito Ortiz, and Rashad Evans.

The Shevchenko sisters hail from Russia but Valentina has been fighting out of Peru for a long time now. Valentina is the more accomplished sister as she is a former multiple-time Muay Thai and Kickboxing world champion.

She made her UFC debut in 2018 by defeating Ji Yeon Kim via unanimous decision. Antonina is 2-1 inside the UFC octagon.

Showtime has a total of eight post-fight bonuses from the UFC.
Sergio Pettis is the younger sibling and is also known as Baby Pettis. He fought as a bantamweight and flyweight division in the UFC but was never able to gain enough success to stay long. He signed with Bellator in 2019 and made his promotional debut last January by submitting Anthony Khaskhasyan.
Dominick and Alex Reyes
Dominick is the #1 ranked light-heavyweight contender in the UFC and is coming off a controversial loss to Jon Jones at UFC 247.
