Mercedes Justine Kaestner-Varnado (born January 26, 1992) is an American professional wrestler and actress. As a wrestler, she has been signed to All Elite Wrestling (AEW) since January 2024, where she performs under the ring name Mercedes Moné ( moh-NAY) and is the current AEW TBS Champion in her first reign. She also appears in New Japan Pro-Wrestling (NJPW) and its sister promotion World Wonder Ring Stardom, where she is the current Strong Women's Champion in her first reign. Varnado became widely known for her time in WWE from 2012 to 2022, where she performed under the ring name Sasha Banks. She is the first and only female professional wrestler to win championships across WWE, AEW, and NJPW.

Varnado began her wrestling career in 2010 on the independent circuit, most notably for Chaotic Wrestling, where she won the Chaotic Wrestling Women's Championship. She signed with WWE in 2012 under the ring name Sasha Banks and was assigned to the developmental territory NXT. She would later win the NXT Women's Championship. Her match against Bayley at NXT TakeOver: Respect in October 2015 was the first women's match to ever headline an NXT TakeOver, the first iron woman match in WWE history, and the longest women's match in WWE history at the time, lasting 30 minutes. Their match was named "Match of the Year" by Pro Wrestling Illustrated (PWI), with Varnado also being named "Woman of the Year".

In 2015, Varnado was promoted to WWE's main roster, where she went on to hold the WWE Raw Women's Championship five times. In 2016, she and Charlotte Flair became the first women to headline a WWE pay-per-view event, the first to compete in a Hell in a Cell match, and the first to win the PWI award for Feud of the Year. In 2019, she won the inaugural WWE Women's Tag Team Championship with tag team partner, Bayley, at Elimination Chamber. In 2020, she won the WWE SmackDown Women's Championship at Hell in a Cell, becoming a WWE Women's Grand Slam Champion and WWE Women's Triple Crown Champion. That year, she was named "Wrestler of the Year" by Sports Illustrated. At WrestleMania 37, Varnado and opponent Bianca Belair became the first two black women to headline a WrestleMania. After creative issues in 2022, Varnado walked out of WWE and was unable to negotiate a new contract. She made her debut for NJPW/Stardom at Wrestle Kingdom 17 in January 2023 under the ring name Mercedes Moné and became a one-time IWGP Women's Champion. After her NJPW/Stardom contract ended in December that year, she signed with AEW the following month and made her debut at Dynamite: Big Business in March 2024, subsequently winning the AEW TBS Championship in her AEW in-ring debut at Double or Nothing two months later.

Outside of wrestling, Varnado portrays the recurring character Koska Reeves in the second and third seasons of the Disney+ space western series The Mandalorian.
