Oceanus is a term that has multiple definitions depending on the context, but it is primarily known as a proper noun referred to in Greek mythology. In Greek mythology, Oceanus was the eldest of the Titans and represented the divine personification of the world's oceans and bodies of water. He was the son of Uranus and Gaia, and the brother and husband of Tethys. Oceanus was depicted as a colossal river that encircled the entire earth and was believed to be the source of all freshwater. He was often depicted as a bearded god riding a sea monster or as a bull with the lower body of a serpent.
In scientific usage, Oceanus is also the name given to a vast oceanic region on Saturn's moon, Titan. This moon's hydrocarbon lakes and seas, collectively referred to as "Oceanus," are named after the mythical Greek deity.

The word "oceanus" has its origins in ancient Greek. It comes from the Greek word "ōkeanos", which referred to the great river believed to encircle the Earth in ancient Greek mythology. In Greek cosmology, the "ōkeanos" was a supernatural realm of water from which all rivers, springs, and seas derived. The term was later adopted into Latin as "oceanus", retaining its meaning as the vast expanse of saltwater surrounding the land.
