Ahrntal (German pronunciation: [ˈaːɐ̯ntaːl]; Italian: Valle Aurina [ˈvalle auˈriːna]) is a comune (municipality) in South Tyrol in northern Italy, located about 70 kilometres (43 mi) northeast of the city of Bolzano (Bozen), near the border to Austria.

Weißenbach is composed of picturesque Alpine farmhouses, grouped around the foaming white glacial stream from which its name is derived.

Amongst the most important mountains in the municipality are the Turnerkamp (3,418 m), the Hornspitzen, the Schwarzenstein (3,369 m), the Großer Löffler (3,379 m), the Wollbachspitze (3,210 m) and the Napfspitze (3,144 m).

The ranges to the west and southwest, including the Speikboden massiv, separate the village of Ahrntal from Mühlwald in the Mühlwalder Tal.

Also of note are both the modern extension to the church building and the newly arranged adjoining cemetery.
