Macarius Magnes (Greek: Μακάριος Μάγνης) is the author of an apology against a Neo-Platonic philosopher of the early part of the fourth century, contained in a manuscript of the fifteenth century discovered at Athens in 1867 and edited by C. Blondel (Paris, 1876). This work (called Ἀποκριτικός πρὸς Ἕλληνας in Greek; Apocriticus in Latin) agrees in its dogmatics with Gregory of Nyssa, and is valuable on account of the numerous excerpts from the writings of the opponent of Macarius. These fragments are apparently drawn from the lost Against the Christians of Porphyry or from the Lover of Truth of Hierocles.
