Agraeus (, Agraios) was the name of a number of personages from ancient myth, but was primarily known as an epithet of the god Apollo in Greek mythology, which meant "the hunter". After Apollo had killed the lion of Kithairon, a temple was erected to him by Alcathous, son of Pelops, at Megara under the name of Apollo Agraeus (some accounts report that Alcathous himself killed the lion).
