Elisabeth Seitz (born 4 November 1993) is a German retired artistic gymnast. She is the 2022 European champion and the 2018 World bronze medalist on the uneven bars. She is one of the only female gymnasts in history to compete the Def (full-twisting Gienger) release, and her eponymous skill, a full-twisting Maloney. Seitz has also had success in the individual all-around event, where she is the 2011 European silver medalist and an eight-time German national champion (2010–13, 2015, 2017–18, 2021). She is a three-time Olympian, representing Germany at the 2012 Summer Olympics in London, the 2016 Summer Olympics in Rio de Janeiro, where she led her team to a sixth-place finish and placed fourth in the uneven bars final, and the 2020 Summer Olympics in Tokyo. In 2022, she was part of the first German team to ever win a European team medal.

Seitz competed at the 2010 World Artistic Gymnastics Championships, alongside Oksana Chusovitina, Lisa Katharina Hill, Joeline Mobius, Pia Tolle, and Giulia Hindermann. The team placed 11th in the qualifications, meaning they didn't advance to the team final. Seitz, however, qualified to the individual all-around final in 15th place, and to the uneven bars final in 6th place. She finished 12th in the all-around, with a score of 56.157 and came in 8th place in the uneven bars final, after falling on her full-twisting Gienger, called a Def, and her toe-on to piked tkatchev, called a Church, and score a 10.466.

At the 2011 European Championships, Seitz finished second in the all-around behind Anna Dementyeva with a score of 56.700. She finished 5th in the vault final with a score of 14.187. She finished 5th in the uneven bars final with a score of 14.175.

At the 2011 Switzerland-Germany-Romania Friendly, Seitz contributed scores on vault, bars, and beam towards Germany's second-place finish.

At the 2011 World Championships, Seitz contributed scores on all four apparatus towards Germany's sixth-place finish in the team final. In the individual all-around she finished eleventh with a score of 55.823.

Germany finished ninth in the team qualification round, so they did not qualify into the final. They were only 0.365 behind Canada. However, Seitz qualified twelfth into the all-around final, and eighth into the uneven bars final. In the individual all-around final, Seitz finished 10th with a score of 57.365. In the uneven bars final, Seitz finished in sixth with a score of 15.266.

In December 2012 she competed at the 2012 World Cup event in Stuttgart and placed second with a total score of 55.566. A week later she competed in Glasgow and again took silver, this time with a score of 54.799.

After the Olympic season, she competed at the 2013 American Cup and the 2013 World Championships, even though she was not fully prepared due to her studies. She continued competing through the 2014 season. Her World Championship chances were questioned due to injuries, but she made the team. However, she competed only on bars where she had a fall. She later competed at the 2014 Arthur Gander Memorial, finally putting together solid routines and snatched the bronze, behind the silver medalist Larisa Iordache and the gold medalist Daria Spiridonova. She won another bronze along with Fabian Hambüchen at the Swiss Cup behind the Russian and Ukrainian teams.
