Ligia natalensis is an isopod in the family Ligiidae.

[1] The type specimen for this species is held in the KwaZulu-Natal Museum in Pietermaritzburg, South Africa.

Its moderately convex body is twice as long as it is wide, 16–17 millimetres (0.63–0.67 in), with some bumps on the outer "shell"...neither as smooth as L. glabrata nor as granulated as L. diletada.

Its eyes are large and convex, and its long, thin antennae have five sections.

The species' elongated uropods are slightly curved inward.
