Antenor of Athens was a 5th-century BCE Athenian writer. The 10th-century Byzantine encyclopedia, the Suda, records him as a contemporary of the philosopher Democritus, but no further biographical details survive.

The Suda attributes a single, lost work to Antenor titled On the Families, Cities, and Deeds of the Archons. Its title indicates it was a historical compilation concerning Athenian magistrates.

Antenor’s significance derives solely from his mention in the Suda. His work appears to belong to the genre of Atthidography, the local histories of Athens, though he is not counted among its principal authors. The absence of citations in later surviving works suggests his compilation was not influential, making him an example of the many minor local historians whose works are now lost.
