Calvay Castle ({{langx|gd|Caisteal Calbhaigh}}) is a ruined castle on an islet close to the island of Calbhaigh, at the eastern approaches to Loch Boisdale, South Uist. The castle is linked by a causeway from Calbhaigh, which becomes inundated at high tide. The castle is a scheduled monument.{{Historic Environment Scotland|num=SM5853|desc=Castle Calvay,castle,Calvay,Loch Boisdale|access-date=1 April 2019}}

The castle may have been built by the MacRuaries of Garmoran, or by the MacNeils of Barra who were granted the lands of Boisdate in the 15th century.{{Canmore |num=10130 |desc=Calvay Castle |access-date=26 November 2012}} Bonnie Prince Charlie hid at the castle in June 1746, while fleeing from the Duke of Cumberland's troops after the Battle of Culloden.

The island also has a lighthouse, built by David Alan Stevenson in 1891.{{cite web |url=http://www.nlb.org.uk/HistoricalInformation/StevensonEngineers/David-A--Stevenson/ |title=Lighthouses built by David A. Stevenson |publisher=Northern Lighthouse Board |accessdate=26 November 2012}}
