Antigonus of Carystus was a Greek biographer and art critic of the 3rd century BCE. A native of Carystus in Euboea, he was active in Athens and later at the court of Attalus I of Pergamum. He is considered a peripatetic biographer in method and is often distinguished from an earlier sculptor of the same name.

His major work is the Lives of Philosophers, a collection of biographies now lost but preserved in fragments and later citations. He also produced descriptions of artworks, which may have formed a separate work or been part of his biographical writing.

Antigonus is a significant fragmentary source for Hellenistic biography and art history. His Lives was used by later doxographers like Diogenes Laërtius, preserving valuable anecdotes and doctrinal information. His art descriptions provide important testimony for Greek sculpture and painting, and his career reflects the intellectual networks between Athens and Pergamum.
