The greater long-nosed bat or Mexican long-nosed bat (Leptonycteris nivalis) is a species of bat in the family Phyllostomidae.

They are more easily confused with their close relatives, the greater long-nosed bats, but, in addition to being about 10% larger, the latter have shorter, greyish fur, and proportionately longer wings.

Originally described as a subspecies of the greater long-nosed bat, it was later considered a subspecies of the southern long-nosed bat, before being confirmed as a distinct species.

It is sometimes known as Sanborn's long-nosed bat or the Mexican long-nosed bat, though the latter name is better avoided since it is also used for the entire genus Leptonycteris and for one of the other species in it, the greater long-nosed bat (L. nivalis).
