Miles Corbet (1595–1662) was an English politician, recorder of Yarmouth and Regicide.
He was the son of Sir Thomas Corbet of Sprowston, Norfolk and the younger brother of Sir John Corbet, 1st Baronet, MP for Great Yarmouth from 1625 to 1629. He entered Lincoln's Inn and was appointed Recorder of Great Yarmouth.
Miles succeeded his brother John as MP for Yarmouth, England, serving from 1640 to 1653, and signed Charles I's death warrant. In 1644 he was made clerk of the Court of Wards. In 1649 Oliver Cromwell granted the estate of Malahide Castle to Corbet after the Cromwellian Conquest of Ireland. The castle was returned to its ancestral owners in 1660 with the restoration of Charles II. In 1655 Corbet was appointed Chief Baron of the Irish Exchequer.
After the Restoration of Charles II of England in 1660, all the 59 men who had signed the death warrant for Charles I were in grave danger as they were considered regicides. Miles Corbet, like many of the 59, fled England. He went to the Netherlands where he thought he would be safe. However, with two other regicides (John Okey and John Barkstead) he was arrested by the English ambassador to the Netherlands, Sir George Downing, and returned to England under guard. After a trial, he was found guilty and then executed on 19 April 1662. In his dying speech he said:
"When I was first called to serve in parliament I had an estate; I spent it in the service of the parliament. I never bought any king's or bishop's lands; I thought I had enough, at least I was content with it; that I might serve God and my country was that I aimed at."
