Dipteryx odorata (commonly known as "cumaru" or "kumaru") is a species of flowering tree in the pea family, Fabaceae. The tree is native to Central America and northern South America. Its seeds are known as tonka beans (sometimes tonkin beans or tonquin beans). They are black and wrinkled and have a smooth, brown interior. They have a strong fragrance similar to sweet woodruff (Galium odoratum) due to their high content of coumarin.

The word "tonka" is taken from the Galibi (Carib) tongue spoken by natives of French Guiana; it also appears in Tupi, another language of the same region, as the name of the tree. The old genus name, Coumarouna, was formed from another Tupi name for tree, kumarú.
