Corporal of horse (CoH) is a rank in the British Army's Household Cavalry corresponding to sergeant in other regiments.

It is said to stem from the origin of the word sergeant, which comes from the same root as servant.

Since even the lowliest trooper in the Household Cavalry was once a gentleman, it was considered that such a rank was inappropriate.

A corporal of horse wears three rank chevrons surmounted by a metal crown.
