Bes (; also spelled as Bisu, Coptic: Ⲃⲏⲥ), together with his feminine counterpart Beset, is an ancient Egyptian deity worshipped as a protector of households and, in particular, of mothers, children, and childbirth. Bes later came to be regarded as the defender of everything good and the enemy of all that is bad. According to Donald Mackenzie in 1907, Bes may have been a Middle Kingdom import from Nubia or Somalia, and his cult did not become widespread until the beginning of the New Kingdom, but more recently several Bes-like figurines have been found in deposits from the Naqada period of pre-dynastic Egypt, like the thirteen figurines found at Tell el-Farkha

Worship of Bes spread as far north as the area of Syria and as far west as the Balearic Islands (Ibiza) in Spain, and later into the Roman and Achaemenid Empires.
