SS Nyanza is a disused passenger-cargo steamer on Lake Victoria in East Africa.

[2] Bow, McLachlan and Company of Paisley in Renfrewshire, Scotland built SS Nyanza in 1907 for the Uganda Railway.

[2] She was a "knock-down" vessel; that is, she was constructed in the normal fashion at the shipyard in Paisley, then, after all her parts had been marked with identifying numbers, disassembled and transported by sea in kit form to Kenya for reassembly and fit-out.

In 2002 she was owned by a private company, Delship Ltd, that planned to convert her into a motor vessel.

[3] Nyanza's boilers and triple expansion engines are of a similar size to those originally installed in the White Star Line ship SS Nomadic, which was built in 1911 as a tender to RMS Olympic and RMS Titanic.
