Eucalyptus is a genus of trees. Eucalypt is also the common name for seven similar plants from the tribe Eucalypteae, all from Australasia. They are Eucalyptus, Corymbia, Angophora, Stockwellia, Allosyncarpia, Eucalyptopsis and Arillastrum.

There are over 699 species of eucalyptus, and almost all of them are in Australia. Eucalyptus can be found in almost every part of the Australia, and they are adapted to many different habitats. Their distribution has an implication: they must have evolved after Australia lost contact with the rest of Gondwana. Apart from the island of New Guinea, which is historically connected to Australia, and the Philippines, and a couple of small islands, the eucalypts are not naturally found in any other countries.

Many species are known as gum trees because they put out lots of sap from any break in the bark.Eucalypts have many local names, like 'gum trees', 'mallee', 'box', 'ironbark', 'stringybark' and 'ash'.
