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. At the end of the 19th century it was described by Sabine Baring-Gould as abounding in fish and surrounded by numerous remains of the working of flint in the Stone Age.

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, (originally the Bodmin Moor AONB).

The oligotrophic pool is important for its palynological record (or history) of the vegetation since the last ice-age. It is also part of a network of sites in south-west England for the reconstruction of vegetation history. In the fine granitic gravel on the bottom of the pool grows spring quillwort (Isoetes echinospora). At the time of designation in 1951 it was the only known site in Cornwall, but since 1988 has been found in three nearby pools. Growing on the margins of the pool is six-stamened waterwort (Elatine hexandra), a nationally scarce plant in the UK.
