The Mount Sinai gecko (Hemidactylus mindiae) is a species of lizard in the family Gekkonidae.

The natural habitats of H. mindiae are rocky areas, caves, rural gardens, and urban areas.

The Mount Sinai gecko is threatened by habitat loss.

The specific epithet, mindiae, commemorates the late Mindy Baha El Din, an environmentalist and herpetologist from Egypt.

She was the wife of Sherif Baha El Din, also a herpetologist, who described this lizard as a new species.
