Atma Weapon may refer to:
- Ultima Weapon, the equippable weapon from Final Fantasy VI.
- Ultima Weapon, the boss from Final Fantasy VI.
- The third level upgraded versions of the Relic Weapons in Final Fantasy XIV: A Realm Reborn.
Atma is not correctly used of the above, but rather of the boss from Final Fantasy VI, Ultima Buster.
Atma or Ātman is a Sanskrit word that means 'self' in Hindu philosophy. The word Ātman or Atta refers to a self in Buddhism, but this term is occasionally identified as "soul" or "ego". Within Jainism, the word Atman is a philosophical term to identify the soul.
