Legio I Minervia (lit. First Legion "Minervan", i.e., "devoted to the goddess Minerva") was a legion of the Imperial Roman army founded in AD 82 by emperor Domitian (r.  81–96), for his campaign against the Germanic tribe of the Chatti. Its cognomen refers to the goddess Minerva, the legion's protector. There are still records of the I Minervia in the Rhine border region in the middle of the 4th century. The legion's emblem is an image of goddess Minerva.

Legio I Minervia first, and main, camp was in the city of Bonna (modern Bonn), in the province of Germania Inferior. In 89, they suppressed a revolt of the governor of Germania Superior. Due to this, Domitian gave them the cognomen Pia Fidelis Domitiana (loyal and faithful to Domitian) to acknowledge their support.
