Seipp's day gecko (Phelsuma seippi) is an endangered diurnal species of lizard in the family Gekkonidae.

The species is native to northern Madagascar, typically inhabits rainforests, dwells on trees, and feeds on insects and nectar.

[1] Seipp's day gecko is restricted to the native rainforests and avoids bright sun light.

It is largely dependent on bamboo forest, and habitat degradation is a major threat to this species.

In captivity, P. seippi can be fed crickets, wax moth larvae, fruit flies, mealworms, and houseflies.
