Philip Burnett Franklin Agee (July 19, 1935 – January 7, 2008) was a Central Intelligence Agency (CIA) case officer and writer, best known as author of the 1975 book, Inside the Company: CIA Diary, detailing his experiences in the CIA. Agee joined the CIA in 1957, and over the following decade had postings in Washington, D.C., Ecuador, Uruguay, and Mexico. After resigning from the Agency in 1968, he became a leading opponent of CIA practices. He died in Cuba in January 2008.

Agee was born in Takoma Park, Maryland. He graduated from the University of Notre Dame in 1956, and attended the University of Florida College of Law.

Agee stated that his Roman Catholic social conscience had made him increasingly uncomfortable with his work by the late 1960s leading to his disillusionment with the CIA and its support for authoritarian governments across Latin America. He and other dissidents took encouragement in their stand from the Church Committee (1975-6), which cast a critical light on the role of the CIA in assassinations, domestic espionage, and other illegal activities.
