Hägglingen is a municipality in the district of Bremgarten in the canton of Aargau in Switzerland.

The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster.

In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned.

The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415.

The distance to the nearest train station, Dottikon, delayed industrial development of Hägglingen.

By 2003, a number of medium and small businesses, primarily in the plastics industry, offered approximately 520 jobs.
