SS Justicia was a British troop ship that was launched in Ireland in 1914 and sunk off County Donegal in 1918. She was designed and launched as the transatlantic liner Statendam, a new flagship for the Holland America Line (NASM), but the outbreak of First World War delayed her completion. In 1915 NASM agreed to let the United Kingdom acquire her and have her completed as a troop ship.
The ship was completed in 1917 and renamed Justicia, with the intention that Cunard Line would crew and operate her. However, Cunard was unable to raise a crew for her, so the Shipping Controller appointed White Star Line to manage her.
Justicia entered service in April 1917, carrying troops from North America to Europe. She escaped a U-boat attack in January 1918, but sank that July off the coast of Ireland after two U-boats hit her with a total of six torpedoes.
The ship was 90 ft longer and 9 ft broader than NASM's then flagship, the SS Rotterdam (1908), which Harland & Wolff had completed in 1908. Statendam would have been by far the largest NASM had yet owned. Only HAPAG's Imperator-class ocean liner
