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.
