Dunsyre (Scottish Gaelic: Dùn Saghair) is a village in South Lanarkshire, Scotland.

[dubious – discuss] It is located by the burn known as the South Medwin Water.

From 1867 until 1945 Dunsyre was served by a railway branch from Carstairs to Dolphinton, originally built by the Caledonian Railway, and the disused embankment of this runs along the south side of the village close to the church.

This hill has an elevation of 150 metres (500 ft) above the general surface of the lands, and of 401 metres (1,315 ft) above sea level; a small range of gradually diminishing hills branches off towards the west from it, stretching to the parish of Carnwath.

The ornamental garden Little Sparta lies immediately to the west of the village.
