Dùn Beic is a dun located on the Inner Hebridean island of Coll. It is located at grid reference NM15495644 and is thought to date to between 1000 BCE to 1000 CE. The etymology of the dun's name is uncertain; one possibility is that it could be made up of a personal name. The dun appears in local legend as being one of several fortresses held by Norsemen, who were defeated in battle against the ancestor of the Macleans of Coll.
