The Tux-Zillertal, German: Tux-Zillertaler, is an endangered Austrian breed of domestic cattle.

[2]: 317 [1] The two names derive from those of the municipality of Tux in the Tuxertal, and of the neighbouring Zillertal, both in the Tirol region of Austria.

Like the Hérens, it was long selected for the fighting ability of the cows, at the expense of productive characteristics.

[5]: 77  The coat is black or red, with white markings on the pelvis, the root of the tail, the underbelly and on the udder.

[1] As with the Hérens and Évolène breeds of Switzerland, cows are used for cow-fighting contests, and have long been selectively bred for this purpose rather than for productive characteristics, resulting in decreased milk performance.
