CACI International is an American technology company founded in 1962 that works almost entirely for United States defence, intelligence and federal civilian agencies.

Headquartered in Reston, Virginia, the company employs more than twenty thousand people, the majority holding security clearances, and has grown through a steady programme of acquisitions that add differentiated technology rather than headcount alone.
