Antiochus of Athens (Ancient Greek: Ἀντίοχος ὁ Ἀθηναῖος) was an influential Hellenistic astrologer who flourished sometime between the late 1st and mid 2nd century AD.
All the writings of Antiochus are now lost, but substantial fragments and extracts remain.
Antiochus is extensively quoted or paraphrased by later writers, particularly the Neoplatonist Porphyry, and Rhetorius of Egypt.
A parapegma or calendar of star risings and settings and weather changes is also extant.
Porphyry relies heavily on Antiochus for definitions of technical terms used by Ptolemy in Tetrabiblos.
