The paper contains a short overview of species richness and biodiversity of beetles recorded from mountain areas (Carpathians, Sudetes, Swietokrzyskie Mountains) on Polish territory (Tab., Fig.). Mountains in Poland are the most suitable areas for 5120 beetle species (85,5% of all Polish coleopterofauna) representing 116 families. However, the state of knowledge on beetle fauna in particular mountain regions, as well as some beetle families of Poland is diverse. Some areas with long tradition of research, like Tatra, Pieniny, Bieszczady and Beskidy Mountains, as well as some regions of Sudetes, are far better investigated than other regions. Short presentation of species with the highest faunistic value and general conclusions followed by suggestions for further studies are also included.
