Eridanus /ɨˈrɪdənəs/ is a constellation in the southern hemisphere. It is represented as a river; its name is the Latin name for the Po River. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern constellations.

The name Eridanos, derived from the ancient Greek Eridanos, was given by geologists to a river which flowed where the Baltic Sea is now (Overeem, et al., 2002). Its river system was better known as the 'Baltic River System' (Bijlsma, 1981; Gibbard, 1988).
The Eridanos began about 40 million years ago in the Eocene. By about 12 million years ago in the Miocene, the Eridanos had reached the North Sea area where sediments carried by the river built an immense delta. The Eridanos disappeared in the early Middle Pleistocene when the Ice Age glaciers excavated the Baltic Sea bed.
