SS Usoga is a disused cargo and passenger Lake Victoria ferry in East Africa.

Bow, McLachlan and Company of Paisley in Renfrewshire, Scotland built Usoga and her sister ship SS Rusinga in 1913.

Usoga entered service on the lake in 1915 and was a troop ship during the First World War East African Campaign.

[1] After the Armistice she entered civilian service as a Lake Victoria ferry.

In 1975 the East African Railways and Harbours Corporation laid her up at the Lake Victoria port of Kisumu.
