This is a list of the mammal species recorded in the Cayman Islands. There are the mammal species in the Cayman Islands, of which one is believed to be threatened.
The following tags are used to highlight each species' conservation status as assessed by the IUCN:
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Bat species account for about 20% of all mammals.

Rodentia is an order of mammals characterised by two continuously growing incisors in the upper and lower jaws which must be kept short by gnawing. Forty percent of mammal species are rodents, and they are found in vast numbers on all continents other than Antarctica. Rodents have sharp incisors that they use to gnaw wood, break into food, and bite predators. Most eat seeds or plants, though some have more varied diets. Some species have historically been pests, eating seeds stored by people and spreading disease.
The name comes from the Latin word rodens, "gnawing one" (from the verb rodere, "gnaw").
In terms of number of species—although not necessarily in terms of number of organisms (population) or biomass—rodents make up the largest order of mammals. There are about 2,277 species of rodents (Wilson and Reeder, 2005), with over 40 percent of mammalian species belonging to the order.
The Central American agouti has been introduced to the Cayman Islands, and are found in forests, thick brush, savannas, and cultivated areas.
