SS Galeka was a steam ship built in 1899 for the Union-Castle Mail Steamship Company by Harland and Wolff.

[2] Later she was requisitioned for use as a British troop transport and then a hospital ship during the First World War.

On 28 October 1916, while entering Le Havre, HMHS Galeka struck a mine.

She was not carrying patients at the time, but 19 Royal Army Medical Corps personnel died in the sinking.

She was beached at Cap la Hogue, but was a total loss, Union-Castle's first war casualty.
