Dragonstones (竜石 Ryūseki) are magical stones used by Manaketes to transform into their dragon forms in the Fire Emblem series. Each Dragonstone contains the crux of the dragon's power, allowing them to maintain their humanoid Manakete form and still temporarily take on dragon form if needed. Story details in Mystery of the Emblem and Awakening indicate that each Manakete has only one Dragonstone and cannot use any other, but this is contradicted by gameplay mechanics starting from Mystery of the Emblem onward. If a Manakete were to discard or otherwise lose their Dragonstone, they lose the ability to transform entirely.
Several Dragonstones of various elements exist, including Fire, Earth, Flying, Ice, Mage, Divine, and Dark; each allowing their user to transform into the dragon of that tribe (the Firestone turns the user into a Fire Dragon, for example). In Mystery of the Emblem, rather than being used as weapons, these stones function as items that transform their users into the dragon form, allowing them to maintain said form for a set number of turns. In these states, they use unlimited breath "weapons" that correspond to the dragon form that they assume. Enemy dragons operate slightly differently, remaining as dragons after using a stone for an unlimited amount of time.

- In old development notes for Genealogy of the Holy War, it is mentioned that the sacred weapons are forged from Dragonstones. These notes also suggest that the Falchion from the Akaneia Series is forged from Dragonstones as well, but this element is not incorporated into the games involved. This idea contradicts the fact that Falchion is said to be fashioned from one of the fangs of Naga.
- In Nah's S-rank support with Brady in Fire Emblem: Awakening, it is proposed that a Dragonstone could be used to transfer half of a Manakete's life force to a human, calling it the stone's "true power". However, Nah states that she had only heard this second-hand from Nowi, and admits that she does not know if it is true or not.
- Bantu, the male Avatar and male Kana are the only playable males who can wield Dragonstones.
