Landry of Sées was a 5th-century Gallo-Roman bishop who served as the third leader of the episcopal see of Sées. Following the tenures of Latuin and Sigibold, he worked to expand the influence of Christianity within his diocese. Although legends suggest he faced intense opposition, including being rolled down a mountain in a barrel of flax combs, these accounts remain unverified. He passed away on March 4, 480, at an advanced age while in the company of the Bishop of Bayeux.
