Scarabaeus sacer, common name sacred scarab, is the type species of the genus Scarabaeus and the family Scarabaeidae. This dung beetle is native of southern Europe, northern Africa and western Asia, and it was venerated in ancient Egypt.

The genus Scarabaeus consists of a number of Afro-Eurasian dung beetle species, including the "sacred scarab beetle", Scarabaeus sacer and is the namesake of the tribe Scarabaeini, the family Scarabaeidae, the superfamily Scarabaeoidea and the infraorder Scarabaeiformia. These beetles feed exclusively on dung, which they accomplish by rolling a piece of dung some distance from where it was deposited, and burying it in order to feed on it underground. They also prepare food for their larvae by excavating an underground chamber, and filling it with balls that have eggs laid in them. The growing larva feeds upon the dung ball, pupates, and eventually emerges as an adult.
