Age of Mythology: The Titans is an expansion pack to the real-time strategy video game of Age of Mythology. It was developed by Ensemble Studios and released on September 30, 2003. It was followed in 2016 by a second expansion pack to the original game called Tale of the Dragon.

The Titans adds a fourth culture to the game, the Atlanteans, and three new major gods, plus new units, buildings and god powers. It also includes many new features, such as auto-queueing (allows indefinite training of units as long as you have sufficient resources), and the ability to summon a Titan, a gargantuan, godlike being that forms the game's focal point.
