Cradle of Eternity is the debut solo album by Wagakki Band lead vocalist Yuko Suzuhana, released on November 23, 2016, by Avex Trax in three editions: CD only, two-disc CD, and CD with DVD or Blu-ray.

In contrast to Wagakki Band's style of mixing traditional Japanese musical instruments (wagakki) with heavy metal, the album features a more mainstream J-pop sound.

Initial releases of the album included a trading card with a code to download the character Yuko Ortensia (ユーコ・オルテンシア, Yūko Orutenshia) for the PS Vita game SD Gundam G Generation Genesis.

A mu-mo Shop exclusive release included a keychain of Yuko Ortensia.
