The SS Nevasa, also known as HMT Nevasa, was a British troopship built on the River Clyde, Scotland, in 1955 and launched on 30 November 1955. The ship was the first troopship built since the end of the Second World War and the largest troopship at that time to be built in the United Kingdom. The ship was laid up in the River Fal from October 1962 to 1965 when it became an educational cruise ship. The conversion of the ship cost £500,000 and took place in Falmouth, Cornwall. The Oil crisis in 1973/74 and its effect on running costs led to the ship's final cruise in December 1974.
