Puxton Moor (grid reference ST412630) is a 31.07 ha (76.8 acres) biological Site of Special Scientific Interest on the North Somerset Levels, near Puxton, North Somerset, notified in 1994.

It is a large area of pasture land networked with species-rich rhynes, now owned and managed as a nature reserve by Avon Wildlife Trust.

The rhynes contain rare plants such as frogbit and rootless duckweed, along with many scarce invertebrates such as the hairy dragonfly and water scorpion.

[1] The site also contains a relict Roman landscape which is evident in many of the fields; Medieval earthworks are also present.
