"The Derby Ram" or "As I was Going to Derby" is a traditional tall tale English folk song that tells the story of a ram of gargantuan proportions and the difficulties involved in butchering, tanning, and otherwise processing its carcass.

Old Tup, sometimes termed the Derby Tup or the Derby Ram, is a folk custom found in an area of the East Midlands of England. Geographically, the custom was found on the borders of Derbyshire and Yorkshire and stretched into part of Nottinghamshire. The tradition entails the use of a hobby horse with a goat's head that is mounted on a pole and carried by an individual hidden under a sackcloth. It represents a regional variation of a "hooded animal" tradition that appears in various forms throughout the British Isles. In geographical location and style it displays strong similarities with the Old Horse custom, but in the latter the hobby horse was presented as a horse rather than a ram.
