SS Madiana was a passenger and cargo steam ship designed and built in the Robert Napier and Sons shipyard in Glasgow in 1877 as SS Balmoral Castle.

She was sold several times over the next 20 years, being named SS San Augustin between 1882 and 1886, before reverting to Balmoral Castle.

[1] On 16 December 1883 San Augustin caught fire north of La Coruna while on passage from Manila bound for Liverpool.

Her crew abandoned ship, but she stayed afloat and was towed to La Coruna for repairs.

[2] On the morning of 10 February 1903, the SS Madiana was approaching Bermuda after a voyage from New York City.
