Barnet Gate is a hamlet on the northern edge of the London Borough of Barnet to the west of Arkley, in England. There was a settlement there during the Roman occupation of Britain and in the Anglo-Saxon period it was known as Grendeles Gatan (Grendel's Gate or Grendelgate) after Grendel, the monster in the epic poem Beowulf. Manor courts were held there and brickmaking was an important local industry. It was on the edge of Southaw wood which was cleared when nearby Chipping Barnet was developed after which it was known as Barnet Gate. The Gate referred to no longer exists but was either a gate used to prevent cattle straying onto Barnet Common or a gate that marked the boundary between Hertfordshire and Middlesex.
