The Turkish Van is a semi-long-haired breed of domestic cat, which was developed in the United Kingdom from a selection of cats obtained from various cities of modern Turkey, especially Southeast Turkey.
 The breed is rare, and is distinguished by the Van pattern (named for the breed), where the colour is restricted to the head and the tail, and the rest of the cat is white; this is due to the expression of the piebald white spotting gene, a type of partial leucism.
 A Turkish Van may have blue or amber eyes, or be odd-eyed (having one eye of each colour).
 The breed has been claimed to be descended from the landrace of usually all-white Van cats (Turkish: "Van kedisi" ), mostly found near Lake Van, though one of the two original breeders' own writings indicate clearly that none of the breed's foundation cats came from the Van area, which has historically been in Armenia.
