Shell cordovan or cordovan is a type of leather commonly used in high-end shoemaking. Cordovan is an equine leather made from the fibrous flat connective tissue (or shell) beneath the hide on the rump of the horse. The leather derives its name from the city of Cordoba, Spain, where it was first produced by the Visigoths in the seventh century, and later also by the Moors. It is a difficult and expensive leather to make, and in the late 19th and early 20th century was mostly used for razor strops to sharpen razors in barber shops. More recently it has been increasingly used for shoes, wallets, and watch straps due to its aesthetic qualities and exceptional durability. It is also used in archery to protect the fingers. It is smooth and durable, ideal for a finger tab. Shell cordovan has a unique non-creasing characteristic. Because it is made of connective tissue, it is smooth and lacks the pebbled effect of leather derived from animal skin.

Horween Leather Company, the oldest tannery in the United States, is known for its production of shell cordovan and was called the "Cordovan capital of the world" by the Chicago Tribune.
