Genethlius () was a 3rd-century Arab sophist from Petra, Arabia Petraea. His father was also named Genethlius. He was a pupil of the Greek sophists Minucianus () and Agapetus (), and then he himself became a teacher and practiced rhetoric in Athens. He has been known as a rival to the famous Callinicus of Petra. Genethlius is also thought by some scholars to be the author of the first treatise in the corpus of Menander Rhetor.
