SS Tubantia was an ocean liner for Royal Holland Lloyd () built in 1913 by Alexander Stephen and Sons of Glasgow. She was built as a fast mail and passenger steamer for service between the Netherlands and South America. Tubantia was a sister ship of Gelria, also of Royal Holland Lloyd. Germany initially offered a settlement of £300,000—the ship's original cost—to Royal Holland Lloyd, but was rejected. In 1922, an international arbitration committee awarded the company £830,000 compensation from Germany for the loss of the ship.
