The auxiliary ship Olterra was a 5,000 ton Italian tanker scuttled by her own crew at Algeciras in the Bay of Gibraltar on 10 June 1940, after the entry of Italy in World War II. She was recovered in 1942 by a special unit of the Decima Flottiglia MAS to be used as an undercover base for manned torpedoes in order to attack Allied shipping at Gibraltar.
Olterra started life as the tanker Osage. She was built in 1913 by Palmer's Ship Building and Iron Co Ltd, Tyneside, United Kingdom, for a German company. Osage was sold to the Standard Oil Co in New York in 1914 and renamed Baton Rouge. In 1925 she was again sold, this time to the European Shipping Co. Ltd of London and renamed Olterra. As Olterra she passed through the hands of the British Oil Shipping Co. Ltd and in 1930 was bought by Andrea Zanchi in Genoa. On 10 June 1940, when Italy entered World War II by declaring war on France and the United Kingdom, Olterra found herself in the Bay of Gibraltar off Algeciras, Spain. She was sabotaged and partially sunk by British commandos that day.
