Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae. The name also refers to the rigid, naturally biologically inert, resilient, electrically nonconductive, thermoplastic latex derived from the tree, particularly from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.

Palaquium is a genus of about 120 species of trees in the family Sapotaceae. Their range is from India across Southeast Asia, Malesia, Papuasia, and Australasia, to the western Pacific Islands.
