燃えない灰 (Moenai Hai) is a studio album by Japanese experimental band The Gerogerigegege, released in 2016.

The album was recorded between 2014 and 2015, though not entirely written during this period; the second track, ゲロゲリゲゲゲ / The Gerogerigegege, is a rerecording of a piece that previously appeared in the 1986 release The Gero-P as We Got Normal.

[9] Gero 30's current conditions are still unknown; no Gerogerigegege release containing new material since Saturdaynight Big Cock Salaryman lists him in the credits or liner notes as a contributor.

[1] The other review, published several months later, described it in comparison to their earlier work as "still uncompromising", while noting the lack of the humour that had previously characterized the project.

[2] Seattle University radio station KXSU featured it as a staff pick for one of the top albums of 2016.
