Aphodius is a genus of beetles in the family Scarabaeidae.

[2] Aphodius species typically dominate dung beetle communities in north temperate ecosystems.

[3] Most species are functionally classified as endocoprids, also known as dwellers, because the larvae live and feed within the dung pat itself.

[4] With a discovery of an earlier published version by Hellwig, the correct citation for this genus is now: Aphodius Hellwig, 1798 (p. 101; 24 January).

Type species by subsequent designation by Latreille (1810): Scarabaeus fimetarius Linnaeus, 1758.
