List of Sites of Special Scientific Interest in Dorset

This is a list of the Sites of Special Scientific Interest (SSSIs) in the county of Dorset, England, United Kingdom.

In England the body responsible for designating SSSIs is Natural England, which chooses a site because of its fauna, flora, geological or physiographical features.

[1] Natural England uses Dorset's borders to mark one of its Areas of Search.

Natural England, like its predecessor, uses the 1974–1996 county system[3] and as such the same approach is followed here.

The data in the table is taken from Natural England in the form of citation sheets for each SSSI, and the County Background Datasheet for Dorset.
