SS Orcades was an ocean liner serving primarily the UK – Australia – New Zealand route. She started service as a British Royal Mail Ship (RMS) carrying first and tourist class passengers. Orcades carried many migrants to Australia and New Zealand and was later used as a cruise ship, and is featured in the British Pathe films "I am a passenger" on YouTube. She also made several voyages from Canada (Vancouver). "Orcades" is the Latin name for the Orkney Islands.
