Lybster (/ˈlɪbstər/, Scottish Gaelic: Liabost) is a village on the east coast of Caithness in northern Scotland.

By 1859 some 357 boats operated from the harbour, making it the third busiest fishing port in Scotland, only exceeded by Wick and Fraserburgh.

A white-fish fleet operated from the port in the 1900s, but that dwindled too, and now the harbour is used by fishing boats catching lobsters and crabs, and recreational craft.

[6] In 1838, the population was said to be 1312, and there was a move to build a church there, because otherwise worshippers had to travel to either Latheron or Bruan, both about 5 mi (8 km) away.

[7] Lybster declined in importance as a herring fishing port before the First World War as the local industry concentrated in Wick.
