Niederlenz is a municipality in the district of Lenzburg in the canton of Aargau in Switzerland.

The center of the village comes from a middle Bronze Age settlement and a later Roman era farm. However, the modern village of Niederlenz is first mentioned in 924 as de Lencis. In 1261-64 it was mentioned as Nider-Lenz.^[3] The high justice rights were held by Schloss Lenzburg until 1433 when those rights, along with the rights to low justice, were purchased by Bern. Later, the low justice rights reverted to the four villages of Niederlenz, Hunzenschwil, Rupperswil and Staufen. In 1480 village was incorporated with a local government. The village mill was built before 1461 and was pawned by Hans Heinrich of Rinach and then sold in 1486 to Hans von Hallwyl. It was in the possession of the Kull family for generations.

It was originally part of the Staufberg parish. The village got its own church in 1949 and in 1990 became its own parish.^[3]
