The Shetland pony is a Scottish breed of pony originating in the Shetland Islands in the north of Scotland. It may stand up to 107 cm (42 in) at the withers. It has a heavy coat and short legs, is strong for its size, and is used for riding, driving, and pack purposes.

A pony is a type of small horse. Depending on the context, a pony may be a horse that is under a given height at the withers, or a small horse with a specific conformation and temperament. Compared to a larger horse, a pony may have a thicker coat, mane and tail, with proportionally shorter legs, a wider barrel, heavier bone, a thicker neck and a shorter, broader head. The word pony derives from the old French poulenet, meaning foal, a young, immature horse.
