Sellrain is a municipality in the district of Innsbruck-Land in the Austrian state of Tyrol located 14.40 km (8.95 mi) southwest of Innsbruck in the Sellrain Valley.

The River Melach and its tributary the Fotscherbach flow through it.

There are two Catholic churches in the village St. Quirin and St. Anna.

The first settlement developed around the ferruginous healing spring Rothenbrunn, which was used by Innsbruck nobles and citizens since the Middle Ages.

The place name is first mentioned in a document dated 1271 as Selrain.
