Eutropis bibronii, also known commonly as Bibron's mabuya, Bibron's skink, and the seashore skink, is a species of lizard in the family Scincidae.

[1][2] The specific name, bibronii, is in honor of French herpetologist Gabriel Bibron (1806–1848).

The dorsum is olive brown, with a light vertebral stripe which is dark-edged.

A dark dorso-lateral stripe runs from the eye to the base of the tail.

[4] E. bibronii occurs is a fossorial species that has been observed burrowing in low vegetation on sand dunes.
