The kings of Alba Longa, or Alban kings (Latin: reges Albani), were a series of legendary kings of Latium, who ruled from the ancient city of Alba Longa. In the mythic tradition of ancient Rome, they fill the 400-year gap between the settlement of Aeneas in Italy and the founding of the city of Rome by Romulus. It was this line of descent to which the Julii claimed kinship. The traditional line of the Alban kings ends with Numitor, the grandfather of Romulus and Remus. One later king, Gaius Cluilius, is mentioned by Roman historians, although his relation to the original line, if any, is unknown; and after his death, a few generations after the time of Romulus, the city was destroyed by Tullus Hostilius, the third King of Rome, and its population transferred to Alba's daughter city.

The city of Alba Longa, often abbreviated Alba, was a Latin settlement in the montes Albani, or Alban Hills, near the present site of Castel Gandolfo in Latium. Although the exact location remains difficult to prove, there is archaeological evidence of Iron Age settlements in the area traditionally identified as the site. In Roman mythology, Alba was founded by Ascanius, the son of Aeneas, as a colony of Lavinium, the original settlement of Trojan refugees and native Latins, which it quickly eclipsed. There is some uncertainty in the tradition as to Ascanius' mother; in some accounts he was the son of Lavinia, and grandson of Latinus, the native king who welcomed Aeneas and the Trojans; his elder half brother, Iulus, was the son of Creusa, Aeneas' first wife, who died in the sack of Troy. This was the account favoured by Livy; in other versions, Ascanius was the son of Creusa; Dionysius and Virgil follow this account. However, the two differ where Vergil claims Ascanius and Iulus were the same; Dionysius, on the other hand, makes Iulus the son of Ascanius. In all accounts, Ascanius was the founder and first king of Alba Longa, while Iulus was claimed as the ancestor of the Julian gens.
