Dizkuh (Persian: دزکوه‎) or Shahdiz (شاهدز) was a fortress near Isfahan, Iran, notably held by the Nizari Ismailis. It was captured and destroyed in Seljuk sultan Muhammad Tapar's anti-Nizari campaign. Its conspicuous, picturesque ruins lie about 8 km south of Isfahan on a subpeak of Mount Soffeh.

Mount Soffeh or Kuh-e Soffeh is a mountain that is situated just south of the city of Isfahan, southeast of Mount Donbeh and south of the Zayanderud River in Iran.
