Jessica Lauren Graff (born January 12, 1984)[2][3][4] is an American professional stunt woman, martial artist and athletics-based television personality.

In 2017, Graff became the first woman to compete in, and to successfully finish, Stage 2 in Las Vegas, although this was part of the USA vs.

She has stated about her time as a 12-year-old trapeze artist, "The rule was I wasn’t allowed to catch anyone who outweighed me by more than 20 pounds.

[10] Graff started doing stunt work in 2007 and has appeared in several television shows and movies, including X-Men: First Class, Make It or Break It, Another Period, Bridesmaids, Knight and Day, Bad Teacher, John Carter, Leverage, Sons of Anarchy and The Mandalorian.

[9][10] As a stuntwoman, she has done tumbling on Make It or Break It, trampolined on Another Period and has done many stunts on rooftops, the sides of bridges or buildings and dramatic wipeouts.

[8] In the first scene of the 2020 feature film Wonder Woman 1984, young Diana takes part in an Amazon athletic contest that resembles Ninja Warrior; Graff portrays a competitor.

She was the second woman in the show's history to clear Stage 1 (the first being another stuntwoman, Chie Nishimura of Super Sentai, 19 years beforehand at Sasuke 2.)

[citation needed] In season 8, in the Los Angeles qualifying round, she became the first woman in American Ninja Warrior history to make it up the new 14 1/2-foot Warped Wall and moved on to the city finals along with professional rock climber Natalie Duran.

In the Los Angeles city finals, Graff did not complete the course but finished second overall based on the show's "the farthest the fastest" metric.

In 2018, for American Ninja Warrior season 10, she completed the Miami City qualifier course atop the Warped Wall, with a 10th place finish overall for the night.

In the Miami city finals, she made it to the ninth obstacle, the Stair Hopper, before falling, but it was still far enough fast enough to give her a 5th place finish overall and another trip to Las Vegas.

She was ultimately unable to compete at the Las Vegas National Finals due to filming commitments in the Canary Islands for stuntwork on her project, Wonder Woman 1984.

[17] However in the Las Vegas finals, she fell early on Stage 1 when she failed to make the transition halfway through the Double Dipper obstacle (other ninjas had benefited from their experience the previous year with this difficult obstacle, whereas Graff had not that experience due to her Wonder Woman work).

She competed in the first filming, but that was interrupted due to the COVID-19 pandemic, which further allowed her to rest and recover from her medical treatment.

[18] In 2023, Graff made it to the Semi-finals in Season 15, but fell on the 4th obstacle during a head-to-head race against teenager, Jaleesa Himka, and did not make it to the Finals.
