Honoratus (French: Saint Honorat; c. 350 – 6 January 429) was the founder of Lérins Abbey who later became an early Archbishop of Arles.

Encouraged by Leontius of Fréjus, he took up his abode on the wild Lérins Island today called the Île Saint-Honorat, with the intention of living there in solitude.

Thus was founded the Monastery of Lérins, which has enjoyed so great a celebrity status and which was, during the 5th and 6th centuries, a nursery for illustrious bishops and remarkable ecclesiastical writers.

[6] Honoratus' reputation for sanctity throughout the southeastern portion of Gaul was such that in 426 after the assassination of Patroclus, Archbishop of Arles, he was summoned from his solitude to succeed to the government of the diocese, which the Arian and Manichaean beliefs had greatly disturbed.

In the Middle Ages, Honaratus was the object of a pilgrimage in the Arles region, especially around Lérins Abbey, because of the writings in Occitan of Raymond Féraud (or Raimon Feraud), a monk who composed a hagiographical life for him around 1300 in Roquesteron.
