Zella-Mehlis is a town in the Schmalkalden-Meiningen district of Thuringia, Germany.

It is situated in the Thuringian Forest, approximately 5km north of Suhl and 20km east of Meiningen.

Two of Germany's most notable firearm manufacturers, Walther and Anschütz, were founded in Zella-Mehlis.

They operated there until the Soviet occupation of Eastern Germany at the conclusion of World War II caused both companies to move.

In January 2019, the former municipality of Benshausen was integrated into Zella-Mehlis, expanding the town's jurisdiction.
