Trinity Lemyra Thomas (born April 7, 2001) is an American artistic gymnast and a four-time National Team member (2016–20). She was a member of the gold medal-winning team at the 2018 Pan American Gymnastics Championships, where she also won silver medals in the individual all-around and on the uneven bars, as well as the bronze medalist on balance beam and floor exercise at the 2017 national championships. She was a member of the Florida Gators women's gymnastics team. One of the most successful NCAA gymnasts in history, Thomas finished her collegiate career with a record-tying 28 perfect-10 scores and a record-breaking five Gym Slams (scores of perfect 10 on every apparatus).

Thomas commenced gymnastics training in 2008, at the age of 7 – a relatively late start for an elite-level gymnast. In 2011, training at Skyline Gymnastics in York, she was the Pennsylvania state champion for Level 7 in the all-around and on all four pieces. As a result, she skipped Level 8 to compete as a Level 9 gymnast, placing second at the 2012 Regionals. At the 2012 Level 9 Eastern Championship in Maryland, she was fourth in the all-around; she competed against future teammate Sydney Johnson-Scharpf.

For the 2013 season, Thomas moved to Artistic Sports Academy Plus (ASAP) in Harrisburg, Pennsylvania, and moved up to Level 10; the highest level of the USAG program. She was third at States, ninth at Regionals and, as a result, qualified to the J.O. NIT competition. At the competition, held in Minneapolis, Minnesota, Thomas finished fourth in the all-around and was the National Champion on floor.

In 2014, following her move to Prestige Gymnastics in Lancaster, she only competed three events at the Pennsylvania State Championships.

In February 2015, Thomas qualified as a Junior International Elite gymnast through her performance in the WOGA Classic Elite Qualifier.

Thomas became age-eligible for senior-level competition in 2017. She made her senior international debut at the 2017 City of Jesolo Trophy where she helped the USA finish first. In July Thomas competed at the 2017 U.S. Classic. She only competed on uneven bars and balance where she placed third on each. Later in the summer Thomas competed at the 2017 U.S. National Gymnastics Championships where she placed fourth in the all-around behind Ragan Smith, Jordan Chiles, and Riley McCusker, sixth on bars, and third on beam and floor. As a result, she was named to the senior national team and invited to participate in the Worlds Team Selection Camp. After the two days of trials, Chiles and Thomas were selected as the non-traveling alternates for the 2017 Artistic Gymnastics World Championships.

In the beginning of the year Thomas was selected to compete at the Tokyo World Cup, where she won silver behind Mai Murakami of Japan. In April she announced her commitment to the University of Florida and their gymnastics team. In August Thomas competed at the 2018 U.S. National Gymnastics Championships where she placed eighth in the all-around, fourth on bars, and sixth on beam and floor, and was once again named to the senior national team. On August 20, 2018, Thomas was named to the team to compete at the Pan American Championships alongside Grace McCallum, Jade Carey, Kara Eaker, and Shilese Jones. There she won gold in the team final and silver in the all-around and on uneven bars. Thomas was invited to attend the Worlds Team Selection Camp but declined.

In 2019 Thomas became one of the few gymnasts to train both NCAA and elite gymnastics simultaneously. Thomas competed at the 2019 GK US Classic in July, opting to only compete on uneven bars and balance beam. On the two events, she placed sixth and seventh, respectively.
