SS Eider was a 4,179 ton German ocean liner built for Norddeutscher Lloyd in 1884 by John Elder & Co. of Glasgow as the fourth ship in the Rivers class. She had four masts and was a two-funnelled steamer 430 feet (130 m) long, with a crew of 167, and capable of carrying 1,204 passengers. However, she had a short service history, being lost in what is remembered as one of the most impressive and memorable shipwrecks on the coast of the Back of the Wight, a region on the Isle of Wight, England.
