SY Tern, now operating as MY Tern^[a], is a passenger vessel on Windermere, England. Launched in 1891 she was built for the steamer service carrying passengers from the Furness Railway. She underwent several changes in owner as companies were merged throughout the twentieth century, and spent time as a sea cadet training ship during the Second World War. Refitted several times, her original steam engines have been replaced with diesel engines. Tern is the oldest vessel operating on Windermere, and is a member of the National Historic Fleet. She is currently operated by Windermere Lake Cruises as the flagship of their fleet.
