Terrarium, also called glass garden, wardian case, or vivarium, is an enclosure with glass sides, and sometimes a glass top, arranged for keeping plants or terrestrial or semi-terrestrial animals indoors. The purpose may be decoration, scientific observation, or plant or animal propagation.

Many kinds of plants are suitable for these habitats, including bromeliads, African violets and Crassulaceae. Animals commonly held for observation include reptiles, amphibians, insects, spiders, scorpions and small birds.
