Lizardite is a mineral from the serpentine subgroup with formula , and the most common type of mineral in the subgroup. It is also a member of the kaolinite-serpentine group.

Lizardite may form a solid-solution series with the nickel-bearing népouite (pure end-member: ). Intermediate compositions are possible, with varying proportions of magnesium and nickel. However, the lizardite end-member is much more common than pure népouite, a relatively rare mineral most often formed by the alteration of ultramafic rocks.
