Waaq (also Waq or Waaqa) is the name of God in the traditional religion of many Cushitic people in the Horn of Africa.
In Oromo culture, Waaq or Waaqo denotes the single god of the early monotheistic faith believed to have been adhered to by Cushitic groups. This belief system still somewhat exists in some Oromo societies.
With regard to the Muslim Somalis, since no indigenous spiritual group has survived, no ancient deities and spirits are known. Early beliefs can therefore only be hypothesized from certain customs and words, such as waaq (sky-god), an archaic Somali term for god.
