Körmend (Slovene: Kermendin, Prekmurian: Karmadén, German: Kirment) is a town in Vas county (megye), Western Hungary.

The town is especially well known for its castle which used to belong to the Batthyány family, one of the most important aristocrat families of Hungary. Blessed Ladislaus Batthyány-Strattmann (1870–1931), a famous ophthalmologist who was beatified by the Catholic Church, lived in the castle with his family for nearly 10 years. He turned one of the wings of the castle into an ophthalmology clinic where he treated poor patients for free.

Today, the castle belongs to the Hungarian state.
