Charlie Davis is best known as the runner-up of "Survivor 46," where he competed as a member of the Siga tribe. A Massachusetts native, Davis was 25 years old during filming and was pursuing his law degree at Boston College Law School. Before law school, he graduated from Harvard University, where he was a two-time cross-country team captain. His athletic background contributed to his strong performance on the show, where he secured seven challenge wins and lost 22 pounds over the course of the 26-day competition.
Davis formed a notable alliance with fellow contestant Maria Shrime Gonzalez. However, in a surprising turn during the final Tribal Council, Maria voted for Kenzie Petty instead of Davis, contributing to Kenzie's 5–3–0 victory. Post-show, Davis expressed his disappointment over Maria's decision, noting inconsistent explanations from her regarding her vote.
Beyond "Survivor," Davis co-hosted the official podcast "On Fire with Jeff Probst" for its fourth season. He also ran the Boston Marathon in 2024 to raise funds for Casa Myrna, a Massachusetts-based organization dedicated to ending domestic violence.
