Shayna Powless (born January 8, 1994) is an American former professional racing cyclist. She is of Oneida heritage through her father and is a citizen of the Oneida Nation of Wisconsin.
She grew up in Sacramento, California and played a variety of sports whilst growing up, but initially gravitated towards mountain bike racing during her high school years. In 2013, Powless was crowned Under-23 US national mountain bike champion in her first season in that age category.
She took up road bicycle racing when she joined the cycling team at the University of California, Los Angeles. She signed to ride for the UCI Women's Team Virginia's Blue Ridge–Twenty28 for the 2019 women's road cycling season.
She is the daughter of Olympic marathon runner Jen Allred and the sister of fellow racing cyclist Neilson Powless.
She has been in a relationship with Canadian American football player Eli Ankou since 2013, after the couple met at UCLA. The couple got engaged in 2021, and married in 2025.
