Samantha Worthington (née Kinchen) (born November 8, 1995) is an American professional boxer. She held the WBA interim female super-lightweight title from July 2025 until February 2026.
As an amateur, she won a bronze medal in the welterweight category at the 2013 Youth and Junior World Boxing Championships in Bulgaria as well as five national titles.
Worthington turned professional in 2019, and won her debut paid fight with a first round knockout.
In her eighth pro-fight, she won the Universal Boxing Organization female super-lightweight title by defeating YazmÃÂn Rivas on a unanimous decision at the Muhammad Ali Center in Louisville, Kentucky, on 20 January 2024.
In June 2024, Worthington became the first boxer to sign for five-weight world champion Claressa Shields' T-Rex Promotions.
Unbeaten in 11 professional contests, she faced Victoire Piteau for the vacant WBA interim female super-lightweight title at Little Caesars Arena in Detroit, Michigan, on 26 July 2025, as part of the undercard for the Claressa Shields vs Lani Daniels undisputed female heavyweight championship fight. Worthington won via majority decision with two judges awarding her the bout by scores of 99âÂÂ91 and 96âÂÂ94 and the third seeing it as a 95âÂÂ95 draw.
Back at the same venue for her first defense on 22 February 2026, Worthington lost the title to Edith Soledad Matthysse when she retired on her stool at the end of the eighth round.
