Alphonse Elric is a fictional character and one of the protagonists in the Fullmetal Alchemist manga series and its adaptations created by Hiromu Arakawa. Alphonse is a child who lost his body during an alchemical experiment to bring his deceased mother back to life and had his soul attached to a suit of armor by his older brother Edward. As a result, Alphonse is almost invulnerable as long as the armor's seal is not erased, but is unable to feel anything. To recover their bodies, the Elrics travel around their country Amestris to obtain the Philosopher's Stone—an alchemical object that could restore them. In the animated adaptations of Fullmetal Alchemist, Alphonse is voiced by Rie Kugimiya in Japanese. In the English adaptations, he is voiced by Aaron Dismuke in the first series and by Maxey Whitehead in the second.

Fullmetal Alchemist is a Japanese manga series written and illustrated by Hiromu Arakawa. It was serialized in Square Enix's shōnen manga anthology magazine Monthly Shōnen Gangan between July 2001 and June 2010; the publisher later collected the individual chapters in 27 tankōbon volumes. The steampunk world of Fullmetal Alchemist is primarily styled after the European Industrial Revolution. Set in the early 20th century, in a fictional universe in which alchemy is a widely practiced science, the series follows the journey of two alchemist brothers, Edward and Alphonse Elric, who are searching for the philosopher's stone to restore their bodies after a failed attempt to bring their mother back to life using alchemy.
