Engelhardia is a genus of trees in the family Juglandaceae, native to tropical Asia from northern India east to Taiwan, Indonesia and the Philippines. The genus name is commonly misspelled "Engelhardtia", a "correction" made by the original author Carl Ludwig Blume in 1829 and persistent until today, as it was thus entered in the Index Kewensis; the original spelling is Engelhardia.

Fossil record

Engelhardia pollen has been found in deposits of Miocene Age in Denmark.^[2] †Engelhardia orsbergensis leaf fossils have been uncovered from rhyodacite tuff of Lower Miocene age in Southern Slovakia near the town of Lučenec.^[3] †Engelhardia orsbergensis and †Engelhardia macroptera fossils have been uncovered from late Miocene strata in Iceland.^[4]
