SS Cap Polonio was a German 20,576 GRT ocean liner that was launched in 1914 and scrapped in 1935. She worked the Hamburg Südamerikanische Dampfschifffahrtsgesellschaft ("Hamburg South America Steamship Company") route between Hamburg in Germany and Buenos Aires in Argentina. She was named after Cabo Polonio in Uruguay.

In the First World War Cap Polonio was briefly commissioned as the auxiliary cruiser SMS Vineta. As such she was unsuccessful, did not see active service and was returned to her owners.
