Unterägeri is a municipality in the canton of Zug in Switzerland.

It is situated at the western shore of the Ägerisee. Known as Wilägeri, an outlying settlement of Ägeri, the community split in 1798, at the formation of the Helvetic Republic, into two municipalities, Oberägeri and Unterägeri. Mittenägeri lies between the two villages, on the territory of Unterägeri.

Originally smaller than Oberägeri, Unterägeri grew more quickly during Industrialisation, lying at the road from Zug to Schwyz, and it is now significantly larger than Oberägeri.

The worldwide Iten clan, who have members in Australia and many other parts of the world, live on Oberdorfstrasse.
