Sebastian Junger (born January 17, 1962) is an American author, journalist, and documentary filmmaker, most famous for the best-selling book The Perfect Storm: A True Story of Men Against the Sea.
Junger was born in Belmont, Massachusetts. He graduated from Concord Academy in 1980 and received a Bachelor of Arts degree from Wesleyan University in cultural anthropology in 1984. He received a National Magazine Award in 2000 for "The Forensics of War," published in Vanity Fair in 1999. In 1997, with the publication of his work, The Perfect Storm, he was touted as a new Hemingway, and helped usher a renewed interest in adventure non-fiction. At the Sundance Film Festival in 2010, Junger's documentary feature Restrepo won the Grand Jury Prize for a domestic documentary. His most recent book, War, revolves around Junger's time spent with a United States Army platoon in Afghanistan.

He lives with his wife Daniela in New York City, where he co-owns a bar called The Half-King. In early 2007 he reported from Nigeria on the subject of blood oil.
