St. Nikolaus in Wahlen, Catholic church in Wahlen, South Tyrol, Italy.

St. Nikolaus is a church in Wahlen near Toblach that features white walls and traditional South Tyrolean architecture with detailed frescoes. The building combines a simple exterior structure with ornamental interior elements that have been maintained over time.

A church in Wahlen was first documented in 1258. The present St. Nikolaus was built in 1512 by the master builder Andre Firtaler; the choir was rebuilt and the nave enlarged and re-vaulted. Around 1865 the church was restored and baroquised, and since 22 February 1988 it has been a protected monument.

The church is dedicated to St. Nicholas of Myra, the patron saint of travellers and merchants, a choice linked to the old trade route through Wahlen. The neo-Gothic altar by Anton Ortner, with sculptures by Dominikus Trenkwalder, and the pulpit and pews by carpenter Josef Stauder show local craftwork of the late 19th century.

St. Nikolaus stands in Wahlen, a hamlet in the municipality of Toblach in the Puster Valley, in the diocese of Bolzano-Bressanone. The church is a protected monument, listed under number 16450 in the province of Bolzano. Visitors reach it from Toblach by road toward the Wahlen fraction; the building is a parish church, so check local Mass times before planning a look inside.

The bell tower holds four bells: the fourth was cast in 1906 by Bartolomeo Chiappani of Trento, while the other three were cast in 1922 by Luigi Colbacchini, also of Trento. The tower itself is Romanesque in style, and the Christophorus image on it probably dates from around 1600.
