Gilbert Hay, 11th Earl of Erroll PC (13 June 1631 – October 1674) was a Scottish nobleman.

[1] On 1 January 1651, Erroll took part in the Scottish coronation of King Charles II as Lord High Constable of Scotland.

Charles rode to Scone Abbey with William Keith, 7th Earl Marischal on his left and Erroll on his right.

Erroll petitioned this ruling, stating that he had not fought in any battles against England, and such a fine would bankrupt him.

After his death, the countess became chief governess to James Francis, Prince of Wales in Saint-Germain-en-Laye.
