RMS St Helena was a passenger-cargo liner, built in 1963 as Northland Prince, operated by the St. Helena Shipping Company that operated between Britain and South Africa via the British colony of Saint Helena between 1978 and 1990.

St Helena was constructed in 1963 by Burrard Dry Dock in North Vancouver, Canada as the Northland Prince, and operated under that name between Vancouver and Alaska.

[1] She underwent a refit, was renamed St Helena, and entered service in September 1978 on a route from Avonmouth, England to Cape Town, South Africa, calling en route at Las Palmas, Canary Islands, and Jamestown, Saint Helena.

[1] She continued on this route, interrupted by British government service during the Falklands War, until 1990 when she was replaced by a new ship, also named St Helena.

[2] She was laid up for several years, as a planned service in the Indian Ocean never materialized, before being scrapped in 1996.
