Philippe Jorion (1955—2025) was an author, professor and risk manager. He was the author of more than 100 publications on the topic of risk management and international finance, and is credited with pioneering the Value at Risk approach to risk management.

Jorion's works include Financial Risk Manager Handbook and Value at Risk: The New Benchmark for Managing Financial Risk. He served as the Chancellor’s Professor of Finance at the Paul Merage School of Business at the University of California at Irvine and was a managing director at investment firm PAAMCO where he headed the Risk Management group. In 1995, he wrote the book Big Bets Gone Bad on the bankruptcy of Orange County, California, hoping to push voters towards supporting a proposed upcoming tax increase in the region, but the work's publication date was pushed past the special election.
