Jennifer "Jenn" Lyon was one of the competitors in Survivor: Palau. Lyon finished fourth in the competition. Lyon is the first former castaway of Survivor to die.

On January 19, 2010, she died from cancer, which had come back from remission and had metastasized to her bones. She is the first cast member of Survivor to die. The special Surviving Survivor, which aired Thursday, February 4, 2010, just over two weeks after her death, was dedicated to her memory.

Lyon's diagnosis of stage three breast cancer came in 2005. She endured a double mastectomy at the time and then started her chemotherapy.

Austin Carty, a "Survivor: Panama" contestant who dated Lyon in 2007, told US back in January when she passed away that Jenn "was a genuinely selfless, sweet-natured person. She always had a smile. She cared about every person. This has really rocked the 'Survivor' community."

Jenn was an ally of "Survivor: Heroes vs. Villains" contestant Tom Westman during the Palau season. When the final four vote was split between Jenn and Ian, they went to a fire-building challenge and Ian pulled out the win, leaving Jenn with a 4th-place finish. Jenn's website shows that she has been advocating for breast cancer research since her diagnosis 5 years ago.
