Mare Orientale ("eastern sea" in Latin) is a Lunar mare. It is located on the western border of the Moon's nearside and farside and is thus difficult to see from an Earthbound perspective. Images from spacecraft have revealed it to be one of the most striking large scale lunar features, resembling a target ring bullseye.
