Magden (Swiss German: Magde) is a municipality in the district of Rheinfelden in the canton of Aargau in Switzerland.

They owned the land and exercised the Zwing und Bann rights over the entire village.

With the Act of Mediation in 1803, the entire Fricktal, including Magden, joined the newly created Canton of Aargau.

In 1036, Count Ulrich I von Lenzburg granted the patronage right over the village church to the monastery at Beromünster.

The monastery church was consecrated in 1509 and in the late 16th Century a convent for nuns was added.

Toward the end of the 19th Century fruit (especially cherries) orchards replaced the traditional vineyards.

After World War II, the chemical industry moved into the Fricktal offering many new jobs.
