The Cleveland Bay is a breed of horse that originated in England during the 17th century named after its colouring and the Cleveland district of Yorkshire. It is a well-muscled horse with legs that are strong but short in relation to the body. The horses are always bay in colour although a few light hairs in the mane and tail are characteristic of some breed lines. It is the oldest established horse breed in England and the only non-draught horse developed in Great Britain.
