Rachael Joy Denhollander (née Moxon; born December 8, 1984) is an American lawyer and former gymnast. She was the first woman to publicly accuse Larry Nassar, the former Michigan State University and USA Gymnastics doctor, of sexual assault. Denhollander is 2018 Glamour Woman of the Year and was included in Time magazine's 100 Most Influential People of 2018. She is the recipient of the 2021 Abraham Kuyper Prize for Excellence in Reformed Theology and Public Life.

Denhollander told the MSU Police Department in August 2016, filed a Title IX complaint with the university and then shared her story of sexual abuse with the Indianapolis Star. Denhollander said Nassar sexually assaulted her when she sought treatment for lower back pain as a 15-year-old gymnast.

Denhollander came forward 16 years after Nassar first abused her, which led to a floodgate of hundreds of other women who came forward with similar allegations against him. At least seven other young women told someone about Nassar over a twenty-year period before Denhollander did likewise, but her complaint was the first to gain traction. Nassar initially denied the accusations, then admitted guilt in a plea agreement and now is imprisoned for the rest of his life. Before he was sentenced, more than 200 women gave testimonies about his abuse in two courtrooms over nine days in county courtrooms near Lansing. Denhollander was the last to speak during both of Nassar's sentencing hearings.
