Ciomadul (Hungarian: Csomád) is a dormant volcano in Romania. It is in the Eastern Carpathians, between the spa towns of Băile Tușnad and Balvanyos. Ciomadul lies at the southeastern end of the Carpathian volcanic chain and it is the youngest volcano of the Carpatho-Pannonian region. Ciomadul consists of several lava domes with two embedded explosion craters known as Mohoș and Sfânta Ana, the latter of which contains a crater lake, Lake Sfânta Ana. The dominant volcanic rock at Ciomadul is potassium-rich dacite.
