Mountain and moorland ponies form a group of several breeds of ponies and small horses native to the British Isles. Many of these breeds are derived from semi-feral ponies kept on moorland or heathland, and some of them still live in this way, as well as being kept as fully domesticated horses for riding, driving, and other draught work, or for horse showing.
Mountain and moorland classes at horse shows in the British Isles cover most of the breeds; however, the four closely related Welsh breeds often form their own classes.
Traditionally, the modern mountain and moorland ponies have been regarded as including nine breeds (the four Welsh types being counted as one). Larger native British Isles horses (such as the various large draught breeds) are not regarded as belonging to the mountain and moorland group.
