The Carpathian newt is native to the eastern part of the Carpathian Mountains and the eastern part of the Sudetes Mountains where it is found at altitudes of up to about above sea level. It has been introduced into the Bavarian Forest in Germany. Where their ranges overlap, it often hybridises with the smooth newt (Lissotriton vulgaris), the offspring being intermediate in appearance between the two species. The Carpathian newt prefers wet, shady woodland, both coniferous and broadleaf, glades, woodland edges and upland pastures. It is able to adapt to some extent to degraded habitats, and it breeds in permanent and temporary bodies of water.
