The Lord High Constable of England is the seventh of the Great Officers of State, ranking beneath the Lord Great Chamberlain and above the Earl Marshal.

He was also, in conjunction with the Earl Marshal, president of the Court of Chivalry or Court of Honour. In feudal times, martial law was administered in the court of the Lord High Constable.
