Annie Jacobsen (born June 28, 1967) is an American investigative journalist, author, and a 2016 Pulitzer Prize finalist.

She writes for and produces television programs, including Tom Clancy's Jack Ryan for Amazon Studios, and Clarice for CBS.

Jacobsen is best known as the author of the 2011 non-fiction book Area 51: An Uncensored History of America's Top Secret Military Base, which The New York Times called "cauldron-stirring.

[11] J. R. Seeger, a retired CIA case officer who led the Agency's Team Alpha, the first Americans behind enemy lines after 9/11, reviewed the book, saying: "Jacobsen has a well-deserved reputation as a good writer and an excellent researcher,” but he criticized her attention to detail, and suggested that the book's focus was too general saying that "neither of the topics are discussed in anything resembling the detail required to understand the nuance of covert action".

In 2004, Jacobsen wrote an article about an incident she witnessed with a group of thirteen foreign nationals on board a flight from Detroit to Los Angeles.

The men were identified as twelve Syrians, members of a musical group, and a Lebanese, their promoter; all were traveling illegally on expired visas.
