The Nine Maidens, also known as the Seventeen Brothers, is a Bronze Age stone circle located near the village of Belstone on Dartmoor in Devon, England.

The stone circle functioned as a burial chamber, although the cairn has since been robbed and the cist, known locally as a kistvaen, destroyed.

Samuel Rowe, a nineteenth-century rambler, provided a description of the stones in his 1848 book A Perambulation of the Ancient and Royal Forest of Dartmoor and the Venville Precincts: We shall mount the steep ascent towards Belstone Tor, and within a quarter of a mile, on its western slope, we shall observe the circle called in the neighbourhood Nine Stones, but which in reality consists of seventeen stones, erect, the highest of which is not more than two feet and a half from the ground.

On the side of Belstone Tor, near Oakhampton [sic], is a small grave circle called "Nine Stones."

The Phoenicians worshipped the god of life and fertility Baal with Belstone representing a corruption of 'Baal's ton', that is 'Baal's settlement'.

[8] A poem illustrating the folklore surrounding the stones is recorded in The Witchcraft and Folklore of Dartmoor by Ruth St Leger-Gordon, originally written by Eden Phillpotts in the Book of Avis trilogy: St Leger-Gordon suggests Phillpotts could be referring to another stone circle due to certain inaccuracies in the poem, although these inaccuracies could simply be a generous usage of artistic licence.
