The Electronic Video Agent, or EVA, is a fictional artificial intelligence featured in the science fiction real-time strategy computer game series Command & Conquer.

While it is often used in the game universe as a generic term for all battlefield command and control systems, it actually refers to a specific device, a combined strategic artificial intelligence, intelligence gathering tool, communication system and console interface, giving field commanders an omniscient view of the operational theatre .

The technology was originally developed in the 1950s computer revolution during the war between the European powers and the Soviet Union, and by the first Tiberian War in 1993 was the routine method of battlefield control; by the second Tiberian War in the 2030s, EVA had developed highly sophisticated natural language processing abilities and intelligent thought sufficient to make complex strategic and tactical decisions traditionally assigned to experienced commanders.

The original and authentic version of EVA is the exclusive property of the United Nations, used by the executive and military arm of the United Nations Security Council, the Global Defense Initiative; pirated versions are known to exist, and have been used by the Brotherhood of Nod where their usual (equivalent) device, the Computer-Assisted Biologically Augmented Lifeform, has not been available..
