Eshmun (or Eshmoun, less accurately Esmun or Esmoun) was a Phoenician god of healing and the tutelary god of Sidon.

This god was known at least from the Iron Age period at Sidon and was worshipped also in Tyre, Beirut, Cyprus, Sardinia, and in Carthage where the site of Eshmun's temple is now occupied by the chapel of Saint Louis.

According to Eusebius of Caesarea, Phoenician author Sanchuniathon wrote that Sydyk, 'The Righteous', first fathered seven sons equated with the Greek Cabeiri or Dioscuri, no mother named, and then afterwards fathered an eighth son by one of the seven Titanides or Artemides. (See Kotharat). The name Eshmun appears to mean 'the Eighth'.

The Neo-Platonist Damascius also stated

The Asclepius in Beirut is neither a Greek nor an Egyptian, but some native Phoenician divinity. For to Sadyk were born children who are interpreted as Dioscuri and Cabeiri; and in addition to these was born an eighth son, Esmunus, who is interpreted as Asclepius.

Photius (Bibliotheca Codex 242) summarizes Damascius as saying further that Asclepius of Beirut was a youth who was fond of hunting. He was seen by the goddess Astronoë (thought by many scholars to be a version of ‘Ashtart) who so harassed him with amorous pursuit that in desperation he castrated himself and died. Astronoë then named the youth Paeon 'Healer', restored him to life from the warmth of her body, and changed him into a god. A village near Beirut named Qabr Shmoun, "Eshmoun's grave," still exists.
