Oškobrh, Natural monument in Central Bohemia, Czech Republic.

Oškobrh is a 287-metre hill and natural monument between the villages of Oškobrh and Vlkov pod Oškobrhem in the Nymburk district. Its protected area covers 100.8 hectares, much of it wooded, with a mouflon-breeding enclosure on part of the hill. Exposed opuka (marlstone) outcrops and dry grasslands lie on its slopes.

The hill was long used intensively: remains of three small churches stand on the northern summit, the oldest from the 13th century, on the site of a hillfort called Kostelíček. An older prehistoric hillfort on Hřebínek lies near the top, and a warrior's grave with a Great Moravian-style battle axe was found northeast below the hill. Opuka stone was quarried here, possibly already in the 10th century for the Slavník hillfort at Libice nad Cidlinou.

The name Oškobrh is pre-Slavic, usually explained from the Germanic aska (ash) and berg (mountain), meaning "ash hill"; it is one of the few pre-Slavic place names in the Czech lands. The hill was a landmark for travellers crossing the flat Polabí lowland, and the name survived later changes of settlement.

The marked hiking trails around the hill are freely accessible and well signposted, allowing visitors to explore the area comfortably. The interior breeding area remains restricted, but the views across the surrounding land compensate for this limitation.
