Sir George Hayes (19 June 1805 – 24 November 1869) was an English judge, a justice of the Queen's Bench.

Hayes, second son of Sheedy Hayes, a West Indian proprietor, by Catherine, daughter of John Westgate, was born in Judd Place, Somers Town, London, and educated at Highgate School and at St. Edmund's Roman Catholic college, near Ware.

In the following December he was appointed Recorder of Leicester, and, on the promotion to the bench of Mr. Justice Mellor, Hayes henceforth divided the lead of the midland circuit with Kenneth Macaulay, Q.C.

Before special juries he was much more successful; every word and gesture usually had their effect, and in the famous Matlock will case, where he was the leader, the decision was greatly due to his extensive knowledge of the law and his masterly dissection of the evidence.

He was the author in 1854 of an elegy in which he humorously lamented the extinction of John Doe and Richard Roe from the pleadings in ejectment.
