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. She was finally sold to the Quebec S.S. Company, Ltd. in 1893 and was renamed Madiana.
