Colonel George Hay, 16th Earl of Erroll (13 May 1767 – 14 June 1798), was a Scottish peer and soldier.

His elder sister, Lady Augusta Hay (the first wife George Boyle, 4th Earl of Glasgow), succeeded to the Etal estate in 1806.

From his father's first marriage to Rebecca Lockhart, he had one half-sibling, Lady Mary Hay, who married General John Scott of Balcomie.

His younger brother was William Hay, later 17th Earl of Erroll, who served as Lord High Commissioner to the General Assembly of the Church of Scotland from 1817 to 1819.

One of the objections he made was that the earldom of Erroll had been claimed through a nomination made by Gilbert Hay, 11th Earl of Erroll (died 1674), in favour of his kinsman Sir John Hay; at a time when in some circumstances Scottish peers could choose their successor; and it had been decided in 1748 in the case of the earldom of Stair that such a power of nomination could not be validly exercised after the Treaty of Union.
