Umhausen is a municipality in the Imst district of state of Tyrol in western Austria.

Its name comes from its great, white, light-reflecting, quartz layers, which allegedly cause the mountain to "radiate" (strahlen).

Ascending the Strahlkogel is difficult and it is thus only rarely visited, unlike the neighbouring 3,287-metre-high Breiter Grieskogel.

In the area of the community lies the tallest waterfall of Tyrol at 150 metres of height.

Moreover, the Vivea Gesundheitshotel Umhausen opened in 2011, which plays a large role in the local economy.
