Spies is a technology in Age of Empires III that can be researched in the Capitol by European civilizations or the Town Center by Native American and Asian civilizations once the Imperial Age is reached. Once researched, it allows the player to see their enemies' Line of Sight.

As with its Age of Empires II version and similar to Blockade, Spies have a variable cost that depends on how many units the enemy has. Each of those units increases the cost by 75 coin, but with no minimum or maximum limit, and are researched almost instantly.
