Andrew Hay, 8th Earl of Erroll (c. 1531 – 8 October 1585) was a Scottish nobleman and politician.

He was the son of George Hay by his first wife, Margaret Robertson. His father inherited the earldom after the death of his uncle, William Hay, 6th Earl of Erroll, who died leaving only a baby girl, Jean Hay.

The Peerage of Scotland is unique in that it allows the titles to descend along the female lines; Jean could have conceivable inherited the earldom as Countess of Erroll. Instead, the crown negotiated for George to inherit, with the condition that he pay 4,000 merks to the sixth earl's widow, Helen, Dowager Countess of Erroll, and that one of his sons marry Jean Hay "at the King’s pleasure."

He married his cousin Lady Jean Hay, c. June 1552, daughter of the sixth Earl of Erroll and had issue. Sir James Balfour Paul writes that documents show King James VI and I frequently getting involved in the Earl of Erroll's family affairs and Erroll's clear displeasure with his interference.

His first wife died in August 1570. In 1581, he married Agnes, daughter of George Sinclair, 4th Earl of Caithness and Elizabeth, daughter of William Graham, 2nd Earl of Montrose. They had three children:

His second wife, Lady Agnes survived him and married Alexander Gordon, son of George Gordon, 5th Earl of Huntly.

On 14 April 1604, the Privy Council of Scotland charged George Hay with having "violently seized upon his stepfather" and helped him captive in the fortress of Blairfudie in Edinburgh. The council ordered him reveal Gordon's whereabouts to his mother; on 14 December 1619 the council formally ordered George to keep the peace with his half-brother, Alexander Gordon, over their mother's estate.

In 1613, William Hay was charged by the Privy Council along with three others (Alexander Hay of Brunthill and his sons Patrick and George) for "violently molesting" his mother. They did not appear in front of the council and were denounced. They were later imprisoned. William Hay was released 7 December 1616.
