Ayumi Miyazaki is a Japanese singer and composer born August 25, 1971. He's best known for his work on the Digimon franchise, where he became the go-to voice for evolution theme songs across multiple series.

In Digimon Adventure, Miyazaki sang "Brave Heart," the iconic evolution theme that fans still associate with the original series. He returned for Digimon Adventure 02 with two evolution tracks—"Break Up" and "Beat Hit!"—before later contributing "The Last Element" as the second evolution theme for Digimon Frontier. Beyond just evolution sequences, he was also featured on the collaborative track "Yuuki o Uketsugu Kodomotachi e" ("To the Children Who Inherit Courage") alongside the other Digimon singers.

Outside of Digimon, Miyazaki sang the theme song "Power Play" for the anime Mushrambo.

Musically, composition runs in the family. His father Naoshi Miyazaki and older brother Michi Miyazaki are both composers in their own right.
