Scrabster (Scots: Scraibster,[1] Scottish Gaelic: Sgrabastair/Sgrabstal)[2] is a small settlement on Thurso Bay in Caithness on the north coast of Scotland.

Scrabster Harbour is an important port for the Scottish fishing industry.

[3] During the Second World War, munitions were ferried to Scapa Flow from Scrabster harbour aboard the 40 ft (12.2 m) pilot cutter Mermaid (registered in King's Lynn and built in 1908), skippered by Antony Bridges.

[4] The NorthLink ferry (MV Hamnavoe) leaves regularly from Scrabster for Stromness in Orkney.

Smyril Line operated a weekly service to the Faroe Islands in the summer months, but this was discontinued in 2008.
