Alexander Lindsay, 4th Earl of Balcarres (died 25 July 1736) was a Scottish peer.
He then transferred, as a captain, to Lord Orkney's regiment and saw much action in Flander, where he was wounded at the siege of St Venant.
He was in Ireland with his regiment at the time his father and brother took part in the Jacobite rising of 1715, which caused him to lose any chance of promotion in the army.
[3] At the general election in 1734, he was returned as one of the sixteen representative peers of Scotland.
As he had no children, he was succeeded by his brother James Lindsay, 5th Earl of Balcarres.
