In Greek mythology, Acragas or Akragas () was a river god said to be a son of Zeus and the Oceanid Asterope. The town of Acragas (modern Agrigento) in Sicily takes its name from the river,Smith, "Acragas"; Stephanus of Byzantium, s. v. Akragantes (Meineke, p. 74, Billerbeck, p. 121). which flows to the east of the plateau on which the town was built.
The name "Acragas" likely originates from the Greek karkinos (crab), due to a large population of crabs in its waters.
