Shiaba (Scottish Gaelic: Siaba) is a ruined township located on the southwestern peninsula of the Isle of Mull, Scotland.

It was awarded the status of Scheduled monument in 1993 due to its significance as a source of information about 18th and 19th century rural life in Scotland.

[1] The name Shiaba is derived from the Gaelic Sia Ba meaning "six cows", a reflection of the area's relative fertility in comparison to other parts of the Ross of Mull.

[1] A possible earlier reference can be found in Bleau's Atlas of Scotland, 1654, which depicts the settlement of 'Shaback' in the approximate location of Shiaba.

A contributing factor to the clearance of the village was the hardship experienced by the people of Shiaba following the failure of the potato crop in 1846 which gave support to the landlord's arguments that removal was in their best interests.
