The Drina Formation ("Drina Formacija") is a stratigraphic unit in Bosnia and Herzegovina and Serbia.[2] It was deposited between the Cambrian and the Carboniferous onto Neoproterozoic basement.[3] It is composed of clastic sediments, limestone and volcanic rocks.[1] The Drina Formation is conformably overlain by the Golja Formation.[3]

The formation is part of the Drina Ivanjica Unit and was overprinted by the Variscan and Alpine Orogeny.[3]

The oldest fossils are acritarch phytoplancton and spores, which indicate a Cambrian to Ordovician age. The youngest fossils are conodonts which indicate Viséan to Namurian age.[3]
