Lochboisdale (Scottish Gaelic: Loch Baghasdail [ɫ̪ɔx ˈbɤːs̪t̪ɪl]) is the main village and port on the island of South Uist, Outer Hebrides, Scotland.

Lochboisdale is within the parish of South Uist, and is situated on the shore of Loch Baghasdail at the southern end of the A865.

The pier area has undergone a transformation; the old shop and surrounding buildings were either renovated or removed to provide new housing and commercial units for rent.

Mooring licences are available for day visiting, monthly and seasonal berths, with inclusive use of the quayside facilities, WiFi, showers and laundry.

London-based restaurant chain Boisdale is named after Lochboisdale, having been founded in 1987 by Ranald Macdonald, the eldest son of the 24th Chief of Clanranald.
