While he is most readily associated with the Moabites, according to Judges 11:23-24 he seems to have been the national deity of the Ammonites as well.
According to the Hebrew Bible, the worship of this god, "the abomination of Moab," was introduced at Jerusalem by Solomon (1 Kings 11:7), but was abolished by Josiah (2 Kings 23:13). (Eleventh-century Jewish commentator Rashi quotes a tradition that Solomon's wives built the temples to Chemosh and other deities, and that Solomon is considered responsible for not stopping them.) On the Moabite stone, Mesha (2 Kings 3:5) ascribed his victories over the king of Israel to this god, "and Chemosh drove him out from before me."
The national god of the Moabites. He became angry with his people and permitted them to become the vassals of Israel; his anger passed, he commanded Mesha to fight against Israel, and Moabitish independence was reestablished (Moabite Stone, lines 5, 9, 14 et seq.). A king in the days of Sennacherib was called "Chemoshnadab" ("K. B." ii. 90 et seq. ; see Jehonadab). Chemosh was a god associated with the Semitic mother-goddess Ashtar, whose name he bears (Moabite Stone, line 17; compare Barton, "Semitic Origins," iv.). Peake wrongly holds that Ashtar-Chemosh was a deity distinct from Chemosh, while Moore and Bäthgen (Beiträge zur Semitischen Religionsgeschichte, p. 14) regard "Ashtar" in this name as equivalent to "Astarte," who they believe was worshipped in the temple of Chemosh. "Ashtar" is more probably masculine here, as in South Arabia, and another name for Chemosh, the compound "Ashtar-Chemosh" being formed like "Yhwh-Elohim" or "Yhwh-Sebaoth." Whatever differences of conception may have attached to the god at different shrines, there is no adequate reason for doubting the substantial identity of the gods to whom these various names were applied. Hosea ix. 10 is proof that at some period (according to Wellhausen, at the time of the prophet himself) the impure cult of the Semitic goddess was practised at Baal-peor (compare Wellhausen, Kleine Prophetell; Nowack's Commentary; and G. A. Smith, Twelve Prophets, ad loc.). Chemosh, therefore, was in general a deity of the same nature as Baal. On critical occasions a human sacrifice was considered necessary to secure his favor (compare II Kings iii. 27), and when deliverance came, a sanctuary might be built to him (Moabite Stone, line 3). An ancient poem, twice quoted in the Old Testament (Num. xxi. 27-30; Jer. xlviii. 45, 46), regards the Moabites as the children of Chemosh, and also calls them "the people of Chemosh".
The name of the father of Mesha, Chemosh-melek ("Chemosh is Malik" or "Chemosh is king"; compare Moabite Stone, line 1), indicates the possibility that Chemosh and Malik (or Moloch) were one and the same deity. Book of Judges 11:24 has been thought by some to be a proof of this, since it speaks of Chemosh as the god of the Ammonites, while Moloch is elsewhere their god (compare 1 Kings 11:7, 33). Solomon is said to have built a sanctuary to Chemosh on the Mount of Olives (I Kings 11:7, 33), which was maintained till the reform of Josiah (II Kings 23:13). This movement by Solomon was no doubt to some extent a political one, but it made the worship of Chemosh a part of the religious life of Israel for nearly 400 years.

Next CHEMOS, th' obscene dread of MOABS Sons,
From AROER to NEBO, and the wild
Of Southmost ABARIM; in HESEBON
And HERONAIM, SEONS Realm, beyond
The flowry Dale of SIBMA clad with Vines,
And ELEALE to th' ASPHALTICK Pool.
PEOR his other Name, when he entic'd
ISRAEL in SITTIM on their march from NILE
To do him wanton rites, which cost them woe.
Yet thence his lustful Orgies he enlarg'd
Even to that Hill of scandal [the Mount of Olives], by the Grove
Of MOLOCH homicide, lust hard by hate;
Till good JOSIAH drove them thence to Hell.
