The Vihorlat-Gutin Area (in Slovak Vihorlatsko-gutínska oblasť; in Ukrainian known as the Volcanic Ridge, Vulkanichnyi chrebet) is a region of mountain ranges spanning eastern Slovakia, northern Romania, and western Ukraine.
Geologically these ranges are considered part of the Inner Eastern Carpathians group of the Eastern Carpathians.

The Romanian portions of Vihorlat-Gutin Area are considered part of the northern Carpathians of Maramureş and Bucovina (Munţii Carpaţi ai Maramureşului şi Bucovinei).
