Clearchus of Soli (Greek: Kλέαρχoς, Klearkhos) was a Greek philosopher of the 4th-3rd century BCE, belonging to Aristotle's Peripatetic school. He was born in Soli in Cyprus.
He wrote extensively on eastern cultures, and is thought to have traveled to the Bactrian city of Ai-Khanoum (Alexandria on the Oxus) in modern Afghanistan.
