Menziken is a municipality in the district of Kulm in the canton of Aargau in Switzerland.

From the conquest of Aargau in 1415 until the creation of the Helvetic Republic in 1798, the village was under Bernese domination.

At that time, Menziken belonged to the district (German: Oberamt) of Lenzburg.

The Catholic Menziken-Reinach Diaspora parish was created in 1906-07 when St Anne's Church was built in the municipality.

This factory was followed by numerous weavers, spinners and dyers, which until the 19th century provided a major source of income.

Major employers in the early 21st century include the Schlör AG (which had developed from the brewery founded in 1888 and today produce soft drinks, fruit and apple juice) and Alu Menziken, which produces metal goods.
