Rathbeg is a townland in County Antrim, Northern Ireland. It is situated in the civil parishes of Grange of Nilteen and Donegore, both in the historic barony of Antrim Upper.
In 1967 rescue excavations took place in advance of motorway construction (at grid ref: J183882) at the rath site some 2.5 miles north-east of Antrim. The rath had been surrounded by a V-shaped ditch 19 ft wide and 9 ft deep. Fragments of a cordoned souterrain pot were found and a kiln structure and charcoal remains. == See also ==
