Marinus (Ancient Greek: Μαρῖνος ὁ Νεαπολίτης; born c. 440 AD) was a Neoplatonist philosopher, mathematician and rhetorician born in Flavia Neapolis (modern Nablus), Palestine. He was a student of Proclus in Athens. His surviving works are an introduction to Euclid's Data; a Life of Proclus, and two astronomical texts. Most of what we know of his life comes from an epitome of a work by Damascius conserved in the Byzantine Suda encyclopaedia.
