Himerius (Imier, Imerio) of Cremona (d. June 17, ca. 560), also known as Himerius of Amelia or Irnerius, was an Italian bishop. He is venerated as a saint by the Roman Catholic Church and Christian communities of Western Rite Orthodoxy. A native of Calabria, Himerius was a monk at Amelia before being appointed bishop there. He is described as having been an extremely austere, ascetic personality, both in regard to himself and others.
