Dougal is a Scottish masculine given name. It is an Anglicised form of the Scottish Gaelic Dubhghall, or Dùghall. These Gaelic names are composed of the elements: dubh, meaning "black"; and gall, meaning "impostor". The Gaelic names are derived from a byname, said to have referred to a Dane, in contrast to the fairer Norwegians.
