The Bridestones is a chambered cairn, near Congleton, Cheshire, England, that was constructed in the Neolithic period about 3500–2400 BC. It was described in 1764 as being 120 yards (110 m) long and 12 yards (11 m) wide, containing three separate compartments, of which only one remains today. The remaining compartment is 6 metres (20 ft) long by 2.7 metres (8.9 ft) wide, and consists of vertical stone slabs, divided by a now-broken cross slab. The cairn originally had a stone circle surrounding it, with four portal stones; two of these portal stones still remain. The site is protected as a scheduled ancient monument.
