Lusitanian mythology is the mythology of the Lusitanians, the Indo-European people of western Iberia, in the territory comprising most of modern Portugal, Extremadura and a small part of Salamanca.
Lusitanian deities heavily influenced all of the religious practices in western Iberia, namely also in Gallaecia. They mingled with Roman deities after Lusitania was conquered.
Of particular importance and popularity, especially following the Roman conquest, were a number of deities among whom were Endovelicus, Ataegina, Nabia and Trebaruna.
There is hardly any sign of Bandua, Reue, Arentius-Arentia, Quangeius, Munidis, Trebaruna, Laneana and Nabia — all worshipped in the heart of Lusitania — outside the boundary with the Vettones. Bandua, Reue and Nabia were worshiped in the core area of Lusitania (including Northern Extremadura to Beira Baixa and Northern Lusitania) and reaching inland Galicia, the diffusion of these gods throughout the whole of the northern interior area shows a cultural continuity with Central Lusitania.
Two regional deities in Western Iberia do not occur in the region: Crouga, worshiped around Viseu, and Aernus, in the Bragança area. The largest number of indigenous deities found in the whole Iberian Peninsula are located in the Lusitanian-Galician regions, and models proposing a fragmented and disorganized pantheon have been discarded, since the number of deities occurring together is similar to those of other Celtic peoples in Europe and ancient civilizations.
Dii, Lares, Nymphs and Genii, were the main types of divinity worshiped, known from the Latin epigraphy, although many names are recorded in the Lusitanian or Celtiberian languages.
