Mackenzie Lynne Dern[10] (born March 24, 1993) is an American and Brazilian[11] professional mixed martial artist and Brazilian Jiu-Jitsu practitioner currently competing in the women's Strawweight division of the Ultimate Fighting Championship (UFC). She is a former world No. 1 ranked IBJJF competitor, currently ranked 6th among the female divisions.[12] She is an ADCC and no gi BJJ (black belt) World Champion.[13][14][15] As of October 8, 2024, she is #6 in the UFC women's strawweight rankings.[16]

Early life

Dern was born in Arizona, the daughter of Wellington "Megaton" Dias, a highly decorated grappling competitor.[17] As a child, she grew up travelling back and forth between Arizona and her father's native Brazil.[18] Dern is fluent in English and Portuguese. She has stated that Portuguese has become her primary language, explaining that "my dad and stepmom are both Brazilian. My boyfriend speaks Portuguese. I'm speaking Portuguese more than English. I still have lots of interactions in English of course. But I think in Portuguese, anything to do with fight is all in Portuguese in my mind, I dream in Portuguese."[19]

Dern began training by the age of three and practicing with her father and stepmother who is also a black belt, Luciana Tavares. Mackenzie started competing at a young age, and began competing in the adult divisions at 14 years old. She has won a world championship in every belt level as she progressed to black belt rank, and at brown belt she defeated a male Judo black belt on Japanese TV.[20] She was then promoted to black belt by her father in December 2012, three months prior to her 20th birthday.[9][21] She graduated from Ironwood High School in Glendale, Arizona.[22]

Due to her six 1st place finishes at the Asian Open, Mackenzie is the only female Jiu-Jitsu competitor to have won Gold Medals, at Black Belt level, at each of the 5 principal/highest ranking IBJJF Gi Championships - the other events are the Worlds, the Euros, the Pan Ams and the Brazilian Nationals. One of her biggest achievements in BJJ came when she managed to defeat Gabi Garcia despite a huge weight difference, becoming one of the few women to do so.[23]

Legacy Fighting Alliance

Dern was scheduled to make her mixed martial arts debut against Kenia Rosas at Legacy FC 58.[24] She won her debut by unanimous decision.[25]

Dern was scheduled to fight Montana De La Rosa at Legacy FC 61. The bout was initially scheduled to be contested at strawweight, but was later changed to catchweight, as Dern missed weight by 2.8 lbs.[26] She won the fight by a first round submission.[27]

Dern was scheduled to fight Katherine Roy at LFA 6. Dern came in overweight for the second time in a row, missing weight by four pounds, and had to forfeit 20% of her purse.[28] She won the fight by unanimous decision.[29]

Dern withdrew from the 2024 ADCC World Championship, and instead competed against 2022 ADCC world champion Ffion Davies in a superfight at the inaugural Craig Jones Invitational on August 17, 2024.[78] Dern lost the match by submission due to an armbar.[79]

Personal life

Dern was married to professional surfer Wesley Santos.[80] They separated in 2022.[81] After going through divorce proceedings, Dern publicly accused Santos of physical abuse.[82]

In February 2019, Dern announced that she had put her MMA career on hold due to pregnancy. Her daughter was born on June 9, 2019.[83]

According to Dern, she left Black House MMA after a reported incident concerning her original coach, Juan Gomez, where he got into a physical altercation with her husband over a disagreement about money.[4] However, Gomez disputed money being the reason and subsequently both Dern and Gomez were asked to leave the team.[84]
