The Pragian is one of three faunal stages in the Early Devonian epoch. It lasted from 411.2 ± 2.8 million years ago to 407 ± 2.8 million years ago. It was preceded by the Lochkovian stage and followed by the Emsian stage. The most important lagerstätte of the Pragian is Rhynie chert in Scotland.

In North America the Pragian Stage is represented by Siegenian or Deerparkian time.
