Laura Hillenbrand (born May 15, 1967) is an American author of books and magazine articles. Her two bestselling nonfiction books, Seabiscuit: An American Legend (2001) and Unbroken: A World War II Story of Survival, Resilience, and Redemption (2010), have sold over 13 million copies, and each was adapted for film. Her writing style is distinct from New Journalism, dropping "verbal pyrotechnics" in favor of a stronger focus on the story itself.

Hillenbrand fell ill in college and was unable to complete her degree. She shared that experience in an award-winning essay, A Sudden Illness, published in The New Yorker in 2003. Her books were written while she was disabled by that illness. In a 2014 interview, Bob Schieffer said to Laura Hillenbrand: "To me your story – battling your disease... is as compelling as his (Louis Zamperini's) story."
