Weichs (German pronunciation: [vaɪks]) is a municipality in the district of Dachau in Bavaria in Germany.

In addition, there are several smaller villages: Albertshof, Biechlhof, Breitenwiesen, Daxberg, Edenholzhausen, Edenpfaffenhofen, Erlbach, Erlhausen, Hölzböck, Jedenhofen, and Zillhofen.

Weichs is located in a picturesque area of rolling hills leading to the Glonn river.

Each village is a small knot of tidy white homes with red roofs, interspersed with small dairy farms and quaint Bavarian churches and surrounded by lovely fields of barley and corn.

The name of the place can be derived from common Germanic "wīhsą" as well as from the Latin name "vicus", a smaller form of settlement, which linguistically developed through "Wihs" to today's Weichs.

Weichs was also affected by the Thirty Years' War: In 1634, 1646 and 1648, Swedes, Spaniards, French, Imperialist Armies from Vienna, and Bavarians roamed the country, robbing and plundering.

There are several bakeries and small shops, including a pharmacy, mini-supermarket, post office, and horse-riding school.
