The Dinaric Mountains mixed forests are a terrestrial ecoregion of the temperate broadleaf and mixed forests biome in Southeastern Europe, according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency.

It is part of Köppen's temperate type with humid summers (Cfs) and mountain snow climates (Dfs).

Due to snow abundance and avalanching, alpine biotopes are common for all high mountains.

Several small glaciers still persist in the Durmitor and Accursed Mountains ranges, the Dinaric Alps' highest massifs.

The South European flowering ash (Fraxinus ornus) marks the submediterranean zone at region below 600–1000 m (from N to S).
