Ranolus is a genus of beetles in the family Dermestidae from Southeast Asia and Oceania.

[1] It was originally described as a subgenus of Attagenus, containing only the species Ranolus cavernicola.

It was later found to be a separate genus, and was placed in its own tribe, Ranolini, along with Orphilodes.

A second species, Ranolus tenebricola, was described by Jiří Háva in 2014.

[2] Orphilodes was later synonymized with Ranolus.
