Legio II Augusta was a legion of the Imperial Roman army that was founded during the late Roman republic. Its emblems were the Capricornus, Pegasus, and Mars. It may have taken the name "Augusta" from a victory or reorganization that occurred during the reign of Augustus.

The Cantabrian Wars, sometimes also referred to as the Cantabrian and Asturian Wars, were the final stage of the two-century long Roman conquest of Hispania, in what today are the provinces of Cantabria, Asturias and León in northwestern Spain.
