Dozmary Pool is a small lake, in the civil parish of Altarnun on Bodmin Moor, Cornwall, UK. It is situated 16.9 kilometres (10.5 mi) from the sea and lies about 15 kilometres (9.3 mi) north-east of Bodmin and 2 kilometres (1.2 mi) south of Bolventor. It originated in the post-glacial period. The outflow from the pool is into Colliford Lake and is therefore one of the sources of the River Fowey. In the past the name has been spelt as Dozmaré and as Dosmery Pool. The pool and surrounding area was designated a Site of Special Scientific Interest in 1951 for its biological interest and is within the Cornwall Area of Outstanding Natural Beauty.
