SS Scythia was a British steam passenger ship that sailed on the trans-Atlantic route between Liverpool and New York City, and later Boston. The ship was built by James & George Thomson of Clydebank, and launched on 28 October 1874 for the British & North American Royal Mail Steam Packet Company, which became the Cunard Line in 1879.
Scythia was built with an iron hull, with a gross register tonnage of 4,557, and a length of 420.8 feet long. She was powered by a single 600 hp 2-cylinder compound steam engine and had a top speed of 13 knots.
Scythia sailed on her maiden voyage from Liverpool to New York via Queenstown on 1 May 1875, and made her first voyage from Liverpool to Boston on 13 June 1884. She was retired from service in 1898, and was scrapped in Genoa, Italy in 1899.
