Belhaven (Scottish Gaelic: Beul na h-aibhne, meaning mouth of the river) is a village in East Lothian, Scotland, and was originally the ancient port of Dunbar of which town the village has always been a part.

The physical traces of Belhaven's once substantial breakwater and pier were removed by quarrying and recycling.

Six sizeable houses on the edge of the village defined its perimeters and these large properties, set in their own grounds, prevented Dunbar from expanding to join Belhaven, except for a small area in the south eastern corner.

[2] In 1806 a spinning mill was erected at Belhaven but closed after a relatively short time of operations.

In 1815 a factory for cotton goods was established in the former artillery barracks opposite Winterfield Park, which had been purchased from the government.
