SS Sybil was a cargo and passenger Lake Victoria ferry in East Africa.

The Uganda Railway had begun shipping operations on the lake in 1901 with the launch of the 110 ton SS William Mackinnon, built by Bow, McLachlan and Company of Paisley in Renfrewshire, Scotland.

She was a small general purpose vessel but the company wished to establish more substantial ferry operations.

[1] In the 1950s Sybil sank at her moorings but she was raised, restored as a passenger and cargo vessel and in 1956 re-entered service.

[1] In 1967 the East African Railways and Harbours Corporation scuttled her at Kisumu to form a breakwater.
