The Plasy Uplands () are uplands and a geomorphological mesoregion of the Czech Republic. It is located in the Plzeà  and Central Bohemian regions and belongs to the largest mesoregions in the country. The axis of the territory is formed by the Berounka/Mà ¾e River.
The Plasy Uplands is a mesoregion of the Plzeà  Uplands within the Bohemian Massif. The relief is characterised by extensive remnants of Neogene leveled surfaces, structural denudation depressions and river terraces. The uplands are further subdivided into the microregions of Stà ÂÃÂbro Uplands, KaznÃÂjov Uplands, Plzeà  Valley and Kralovice Uplands.

The axis of the territory is formed by the Berounka River and its main source, the Mà ¾e River. The Radbuza flows to the Mà ¾e through the southern part of the uplands. The Stà Âela flows to the Berounka in the north of the uplands. The largest body of water is the Hracholusky Reservoir, built on the Mà ¾e.
Most of the city of Plzeà  lies within the Plasy Uplands. Other notable settlements in the uplands are Stà ÂÃÂbro, Nýà Âany, Dobà Âany, Tà Âemoà ¡ná, HornàBà ÂÃÂza and also Plasy, after which the region is named.
The geologically diverse bedrock is formed by weakly metamorphosed Proterozoic rocks supplemented by Variscan granitoids, by consolidated Permocarbonite and unconsolidated Tertiary sediments, and occasionally by igneous rocks from the Tertiary and Quaternary periods.
The northwestern part of the Plasy Uplands is protected as the Kà Âivoklátsko Protected Landscape Area.
