SS Prinz August Wilhelm was a Hamburg America Line (HAPAG) cargo liner that was launched in Germany in 1902 and scuttled in Colombia in 1918.

To avoid capture by the Entente Powers in First World War she sheltered in neutral Colombia from August 1914 until April 1918, when her crew scuttled her to prevent the United States Shipping Board (USSB) from seizing her.

In September 1905 the Royal Mail Steam Packet Company (RMSP) announced that it would start running a fast passenger service between New York and Jamaica.

[5] On 17 January 1907 Prinz Waldemar ran aground on a reef in Jamaica and was declared a total loss.

[11] By 1912, 92,865 cubic feet (2,630 m3) of her hold space was refrigerated, with machinery made by the American Linde Refrigerating Co.[12] In 1911 the mountaineer Annie Smith Peck sailed on Prinz August Wilhelm from New York to Colón on her way to climb Coropuna in Peru.

[13] For the season from September 1912 to January 1913, HAPAG advertised Prinz August Wilhelm making round trips from New York to Fortune Island (now Long Cay), Santiago, Kingston, Colón, Bocas del Toro, and Puerto Limón.

[14] at 11:00 hrs on 1 August 1914, with the First World War imminent, HAPAG announced the suspension of its Atlas Service.

Her crew dwindled to 35 men, and both her Master and her doctor were taken ill. HAPAG sent a fresh captain by steamship from Colón to take command.

He recruited six men from Curaçao as stokers, and on 12 November moved her along the Colombian coast to Sabanilla in Puerto Colombia to find a better anchorage.

[17][21][22] Prinz August Wilhelm's wreck remains in the bay of Puerto Colombia, at a depth of 18 metres (59 ft).

[18] Artefacts recovered from the wreck are now in the Museo Arqueologico de Pueblos Karib (MAPUKA) in Barranquilla.
