The Shetland sheepdog, often known as the Sheltie and sometimes as the Shetland collie, is a breed of dog in the herding dog group.

Shelties have the herding dog temperament. They are vocal, excitable, energetic dogs who are always willing to please and work hard. They were used in the Shetland Islands for herding and protecting sheep.

They are small to medium dogs, 13–16 inches (33–41 cm) at the withers by AKC Conformation standards, and they come in a variety of colors, such as Sable/White, Tri-color, Blue Merle, and so forth.

Their early history is not well-known. They originally were a small mixed breed dog, often 8-10 inches in height. It is thought that they were a cross of aSpitz type dog from Scandinavia with the local sheepdog. In the early 1900s, James Loggie added a small show Rough Collie to the stock, and the modern Shetland sheepdog was born. The
original name of the breed was Shetland Collie, but this caused controversy among Rough Collie breeders, and the breed's official name was changed to Shetland sheepdog.

The breed was recognized by the English Kennel Club in 1909.
