Apollophanes was a Stoic philosopher who lived during the 3rd century BCE, in the early Hellenistic period. He is a minor figure known primarily through his connection to a more famous contemporary. According to the ancient biographer Diogenes Laertius, Apollophanes was one of the teachers of Arcesilaus, who would later become the head of Plato’s Academy and shift it toward a skeptical philosophy. This association suggests Apollophanes was active in Athens, the center of philosophical debate at the time. Beyond this role, no details of his life or birthplace are recorded.

No writings by Apollophanes survive, and no titles of his works are known. His ideas are not preserved directly but are referenced only in fragments and testimonia by later authors discussing his era. Consequently, his specific philosophical contributions to Stoicism cannot be reconstructed.

His historical importance lies entirely in this link between two major schools of thought. As a Stoic who taught the future founder of Academic Skepticism, Apollophanes represents a point of intellectual contact during a formative period in Greek philosophy. He is remembered not for his own doctrines, but for his connection to a pivotal figure in the development of Hellenistic thought.
