Bethany Meilani Hamilton is an American professional surfer and writer. On October 31, 2003, she survived a shark attack in which her left arm was bitten off; ultimately, she returned to professional surfing and wrote about her experiences in the 2004 autobiography, Soul Surfer: A True Story of Faith, Family, and Fighting to Get Back on the Board. The book was adapted into the 2011 feature film, Soul Surfer. Hamilton attributes her strength to her Christian faith.
Hamilton is also the subject of a 2018 documentary, Bethany Hamilton: Unstoppable, in which she discusses how marriage and motherhood have affected her professional surfing career.
