The Areopagus sermon refers to a sermon delivered by Apostle Paul in Athens, at the Areopagus, and recounted in Acts 17:16–34. The Areopagus sermon is the most dramatic and most fully-reported speech of the missionary career of Saint Paul and followed a shorter address in Lystra recorded in Acts 14:15–17.

The Areopagus is a prominent rock outcropping located northwest of the Acropolis in Athens, Greece. Its English name is the Late Latin composite form of the Greek name Areios Pagos, translated "Hill of Ares". The name Areopagus also referred, in classical times, to the Athenian governing council, later restricted to the Athenian judicial council or court that tried cases of deliberate homicide, wounding, and religious matters, as well as cases involving arson of olive trees, because they convened in this location. The war god Ares was supposed to have been tried by the other gods on the Areopagus for the murder of Poseidon's son Halirrhothius.
