Brdská oblast is a geomorphological region in Central Bohemia featuring diverse landscapes from rolling plateaus to deep valleys and steep ravines. The terrain includes forested areas, limestone hills, and water sources carved by river systems throughout the landscape.

The name Brdská oblast comes from the Brdy highlands, whose summit Tok reaches 865 m, the highest point of the whole unit. The region was defined in Czech geomorphology as part of the Poberounská subprovince, divided into five units: Džbán, Pražská plošina, Křivoklátská vrchovina, Hořovická pahorkatina and Brdská vrchovina. Its lowest point, 170 m, lies in the Vltava valley near Chvatěruby.
