According to [[Plants of the World Online]], there are more 715 species of plants in the genus ''Eucalyptus'' and most are native to Australia; a very small number are found in adjacent areas of [[New Guinea]] and [[Indonesia]].<ref name="PoWO">{{cite web |title=''Eucalyptus'' |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:27534-1#children |publisher=Plants of the World Online |access-date=25 January 2025}}</ref> One species, ''[[Eucalyptus deglupta]],'' ranges as far north as the [[Philippines]]. Of the 15 species found outside Australia, just nine are exclusively non-Australian. Species of ''Eucalyptus'' are cultivated widely in the tropical and temperate world, including the [[Americas]], [[Europe]], [[Africa]], the [[Mediterranean Basin]], the [[Middle East]], [[China]], and the [[Indian subcontinent]]. However, the range over which many eucalypts can be planted in the temperate zone is constrained by their limited cold tolerance.<ref name="Sellers1910" />

Australia is covered by {{convert|92000000|ha|acre}} of eucalypt forest, comprising three quarters of the area covered by native forest.<ref>{{cite web|url=http://www.agriculture.gov.au/abares/forestsaustralia/profiles/eucalypt-forest|title=Eucalypt forest|access-date=29 January 2017|publisher=Commonwealth of Australia|year=2017}}</ref> The [[Blue Mountains (New South Wales)|Blue Mountains]] of southeastern Australia have been a centre of eucalypt diversification;<ref name="UNESCO_BlueMountains">{{cite web |url=https://whc.unesco.org/en/list/917|title=Greater Blue Mountains Area|date=2019|website=whc.unesco.org|publisher=UNESCO World Heritage Centre|access-date=2019-05-11}}</ref> their name is in reference to the blue haze prevalent in the area, believed derived from the volatile [[terpenoid]]s emitted by these trees.<ref name="Bohlmann2008">{{cite journal|last1=Bohlmann|first1=J.|last2=Keeling|first2=C.
