Honorius of Autun (died c. 1151) was a very popular 12th century Christian theologian who wrote prolifically on many subjects. He wrote in a non-scholastic manner, with a lively style, and his works were approachable for the lay community in general. He was, therefore, something of a popularizer of clerical learning.

Very little is known of his life. He says that he is Honorius Augustodunensis ecclesiae presbyter et scholasticus, but nothing else is known. "Augustodunensis" was taken to mean Autun, but that identification is now generally rejected. However, there is no solid reasoning for any other identification, so his by-name has stuck. It is certain that he was a monk and that he traveled to England and was a student of Anselm's for some time. Toward the end of his life, he was in a monastery in southern Germany, probably living as a recluse.

Among his works are:

• Elucidarium: a survey of Christian beliefs (written in England). It was translated frequently into vernacular, beginning with a translation into Anglo-Saxon.
• Sigillum sanctae Maria: a set of lessons for how to celebrate the Assumption, together with a commentary on The Song of Songs, which he sees as being principally about Mary.
• Gemma animae: An allegorical view of the liturgy and its practices.
• A commentary on The Song of Songs, which sees it as pertaining to Christ.
• A long commentary on the Psalms.
• Clavis physicae, comprised of extracts from Johannes Scotus Erigena.
• De luminaribus ecclesiae: a bibliography of Christian authors, which ends with a list of twenty-one of his own works.

His most important work was the Imago mundi, an encyclopedia of popular cosmology and geography. It was translated into many different vernacular languages and was very popular throughout the medieval period. It contained, among other things, a scheme for the operation of guardian angels.
