Pseudo-Apuleius is the name given in modern scholarship to the author of a 4th-century herbal known as Pseudo-Apuleius Herbarius or Herbarium Apuleii Platonici. The author of the text apparently wished readers to think that it was by Apuleius of Madaura (124–170 CE), the Roman poet and philosopher, but modern scholars do not believe this attribution. Little or nothing else is known of Pseudo-Apuleius.
The oldest surviving manuscript of the Herbarium is the 6th-century Leiden, MS. Voss. Q.9. Until the 12th century it was the most influential herbal in Europe, with numerous extant copies surviving into the modern era, along with several copies of an Old English translation. Thereafter, it was more or less displaced by the Circa instans, a herbal produced at the school of Salerno. "Pseudo-Apuleius" is also used as a shorthand generic term to refer to the manuscripts and derived works.
