Gregentios (Greek: Γρηγέντιος) was the purported archbishop of Ẓafār, the capital of the kingdom of Ḥimyar, in the mid-6th century, according to a hagiographical dossier compiled in the 10th century. This compilation is essentially legendary and fictitious, although a few parts of it are of historical value. Written in Greek, it survives also in a Slavonic translation. The three works in the dossier are conventionally known as the Bios (Life), Nomoi (Laws) and Dialexis (Debate). The whole dossier is sometimes known as the Acts of Gregentios.
