Philiscus of Miletus (Φιλίσκος ὁ Μιλήσιος) was a Greek orator and rhetorician active in the late 5th and early 4th centuries BCE. He was a student of the sophist Isocrates and is identified as one of the teachers of the orator Demosthenes [1]. No further details of his life are recorded.

He is credited with a single oration, which is now lost [1]. No title, content, or fragments of the work survive.

His significance derives from his position within a key pedagogical lineage of Athenian rhetoric. As a student of Isocrates and a teacher of Demosthenes, Philiscus represents a direct link in the transmission of sophistic and rhetorical education between these two major figures [1].
