Jenna Morasca (born February 15, 1981) was a reality TV contestant who was the million-dollar grand prize winner of Survivor: The Amazon.

Morasca also appeared on Survivor: All-Stars. However, in the third episode, she quit the game to be with her dying mother. Her mother passed away the following week from breast cancer.

Morasca's performance on Amazon was made notorious when she stripped down to the flesh for nothing more than peanut butter and Oreo cookies. Morasca was extremely unpopular with many viewers due to her comments about older women and her treatment of other players, leading Morasca to note that she would be remembered as "that bitch who took her clothes off." Her nude exploits won her a spread in Playboy magazine. Morasca appeared near-nude in an ad for PETA with her boyfriend, Survivor: Africa winner Ethan Zohn. In 2005 Morasca replaced Richard Hatch as co-host (with Dalton Ross ) of CBS' Survivor Live, a talk show devoted to the current season of the series.
