JJ Aldrich Bio
JJ Aldrich (born September 29, 1992) is an American mixed martial artist who competes in the Flyweight division. She is currently signed with the Ultimate Fighting Championship (UFC) and has also competed for Invicta FC. As of July 15, 2025, she is ranked #14 in the UFC women’s flyweight rankings.
Aldrich is trained out of Elevation Fight Team and continues to live and train in Denver, Colorado. She holds a 3rd degree black belt in taekwondo and a brown belt in Brazilian Jiu-Jitsu, reflecting the diverse skill set she has developed since childhood.
Early Life and Background
JJ Aldrich was born to a single mother in Denver, Colorado, and grew up in homeless shelters alongside her mother and older sister. Her father had been imprisoned before she was born, which left the family without a stable income during her earliest years. Years later, Aldrich’s mother built a small childcare business, and the additional income allowed the family to leave the shelter system.
When she was nine, Aldrich’s mother enrolled her and her sister in taekwondo classes at a local recreation center. By the age of thirteen, Aldrich had earned her black belt in the discipline. Aldrich is of Irish ancestry.
Around the same period, her taekwondo instructors introduced her to 303 Training Center, an MMA gym in Denver where she began learning mixed martial arts. That gym became the foundation of her combat sports development, and she has remained connected to the same training community ever since.
Path to MMA
In 2010, Aldrich began seeking amateur bouts and quickly compiled several amateur titles across smaller organizations. During that amateur run, she shared the cage with future UFC fighters such as Raquel Pennington, Kailin Curran, and Rachael Ostovich, an early indication of the talent she would face at the top level of the sport.
Her amateur accolades, combined with her taekwondo background and growing ground game, helped her transition smoothly into the professional ranks. By 2014, she was ready to debut on one of the most respected all-women’s MMA stages.
JJ Aldrich Career
Early Career (2014-2016)
JJ Aldrich made her professional MMA debut on September 6, 2014, at Invicta FC 8: Waterson vs. Tamada, where she won by unanimous decision (30-27, 30-27, 30-26). A year later, on February 27, 2015, at Invicta FC 11: Cyborg vs. Tweet, she dropped a first-round submission loss to Jamie Moyle via rear-naked choke. She rebounded in September 2015 at Invicta FC 14, stepping in on short notice against Rosa Acevedo and finishing her with a first-round knockout to earn a Performance of the Night bonus.
In 2016, Aldrich appeared on The Ultimate Fighter: Team Joanna vs. Team Cláudia, defeating Kristi Lopez by unanimous decision in the elimination round before losing to Tatiana Suarez in the quarterfinals by second-round rear-naked choke. She also fought once under the Freestyle Cage Fighting banner in September 2016, stopping Kathina Caton in round one via technical knockout, and returned to Invicta in November 2016, taking a unanimous decision over Lynn Alvarez to collect her second Invicta Performance of the Night bonus.
UFC Breakthrough (2016-2019)
Aldrich signed with the UFC in late 2016, debuting as a late replacement against Juliana Lima at UFC Fight Night: Lewis vs. Abdurakhimov in Albany, New York, on December 9, 2016. She lost that bout by unanimous decision but quickly bounced back, taking a unanimous decision over Chan-Mi Jeon in June 2017 at UFC Fight Night: Lewis vs. Hunt in Auckland, New Zealand.
In 2018, Aldrich added two more unanimous decision wins, defeating Danielle Taylor at UFC Fight Night: Stephens vs. Choi and Polyana Viana at UFC 227. After competing at strawweight through her early UFC run, she returned to flyweight in March 2019, losing a second-round technical knockout to Maycee Barber at UFC Fight Night: Thompson vs. Pettis. She closed 2019 with a unanimous decision win over Lauren Mueller at UFC on ESPN+ 19, establishing herself as a durable decision fighter inside the Octagon.
UFC Flyweight Era (2020-Present)
After a split decision loss to Sabina Mazo at UFC 246 in January 2020, Aldrich began stacking decisions at 125 pounds. She earned a split decision over Cortney Casey at UFC Fight Night 187 in March 2021, then took a unanimous decision over replacement opponent Vanessa Demopoulos at UFC on ESPN 30. In 2022, she outpointed Gillian Robertson at UFC Fight Night 203 before suffering a second-round guillotine choke loss to Erin Blanchfield at UFC Fight Night 207.
In 2023, Aldrich dropped a unanimous decision to Ariane Lipski at UFC Fight Night 221, then closed the year with two consecutive wins, finishing Na Liang via second-round TKO at UFC Fight Night 225 and taking a unanimous decision over Montana De La Rosa at UFC Fight Night 229. After a unanimous decision loss to Veronica Hardy at UFC on ESPN 56 in May 2024, she returned to the win column on March 1, 2025, defeating Andrea Lee by unanimous decision at UFC Fight Night 253. Her scheduled August 16, 2025 bout against Karine Silva at UFC 319 was scrapped when she withdrew for undisclosed reasons.
Driving Style and Strengths
Although she has produced one of her most notable finishes against Na Liang with a ground-and-pound TKO, the bulk of Aldrich’s victories have come by decision, a testament to her cardio, composure, and ability to execute a game plan over fifteen minutes. Her taekwondo base gives her clean striking fundamentals and sharp kicks, while her Brazilian Jiu-Jitsu brown belt adds a credible grappling layer to her game.
Notable Events and Milestones
Aldrich’s UFC career has featured several short-notice opportunities, including her promotional debut against Juliana Lima and last-minute bookings against Rosa Acevedo, Vanessa Demopoulos, and Gillian Robertson. Her second-round TKO of Na Liang in August 2023 stands as one of the most decisive finishes of her professional run.

The performance extended her activity inside a stacked 125-pound division and reinforced her standing as a durable, decision-oriented contender.
As of July 15, 2025, Aldrich sits at #14 in the UFC women’s flyweight rankings, keeping her within striking distance of higher-ranked opponents. Her scheduled August 16, 2025 booking against Karine Silva at UFC 319 was canceled after she withdrew for undisclosed reasons, leaving her next appearance to be determined.
Looking ahead, Aldrich’s combination of experience, grappling depth, and a five-round main card ceiling makes her a consistent gatekeeper in the flyweight division. A return later in 2025 could position her for a ranked matchup as the UFC finalizes its flyweight contender picture.
