Threestoneburn Stone Circle is an archaeological site, a stone circle near the village of Ilderton and about 5 miles (8 km) south of Wooler, in Northumberland, England.

[1] The circle, of the late Neolithic or early Bronze Age, is situated in a large clearing in the modern afforestation of Threestoneburn Wood,[1] formerly overlooking a spacious valley to the east.

There are 16 stones of local pink granite, set about 5.5 metres (18 ft) apart; a larger gap on the east side is thought to be an original entrance.

[1] About 28 metres (92 ft) to the north are two granite stones, one of which is recumbent; immediately to their east is an alignment of three stones lying in the surface layer of peat, 9 metres (30 ft) apart.

A flint tool was found,[1] and spreads of charcoal which may be the traces of fire-rituals.
