Bella Germaniae (English: The History of the Germanic Wars) was a twenty-volume historical work written by the Roman author and commander Pliny the Elder. It is now a lost literary work. The history chronicled the Roman–Germanic wars during the 1st century AD and was written from the perspective of a Roman who had served in Germania.
Bella Germaniae was a significant and respected source, used by later Roman historians such as Plutarch, Tacitus, and Suetonius. Tacitus, in particular, is believed to have used it as a primary source for his own works on the Germanic peoples and wars, including De origine et situ Germanorum and the Annales.
