Orphninae is a subfamily of beetles in the scarab beetle family, Scarabaeidae. There are two tribes in the family, the New World Aegidiini and the Old World Orphnini.[1] They are mostly tropical beetles.[2]

As of 2013 there are about 195 species in the subfamily. They are classified in 15 genera: 4 in the tribe Aegidiini and 11 in the Orphnini. In addition, the genus Stenosternus is provisionally placed in the Aegidiini.[2]
