The Lakeland Terrier is a dog breed, one of many Terrier breeds, that originated in the Lake District of England as a descendant of the old English Black and Tan and Fell Terriers. In 1925 the breed attained homogeneity following a cross-breeding with the Fox Terrier and the Airedale Terrier.

The Lakeland Terrier is suitable for fox and rabbit hunting and sheep protection. The breed is similar to the Welsh Terrier and has thick, hard hair that is colored black and tan, blue and tan, red-gray, red, wheat, liver, blue, or black. They have an upright tail. Lakeland Terriers grow to between 33 and 38cm (13 to 15 inches) in height measured to the shoulder with a weight of between 7 and 8 kg (15 to 17 lbs).
