In Greek mythology, Erebus is the personification of darkness.

The name "Erebus" is also used to refer either to the darkness of the Underworld, the Underworld itself, or the region through which souls pass to reach Hades, and can sometimes be used as a synonym for Tartarus or Hades.

In a number of Greek cosmogonies, Erebus is described as one of the first beings to exist.
