Ebony (Diospyros ebenum), also known as Indian Ebony or Ceylon Ebony, is a tree in the genus Diospyros, native to southern India and Sri Lanka. It is noted for its heavy, black, fine-grained heartwood.

Ebony heartwood is one of the most intensely black woods known, which, combined with its very high density, fine texture, and ability to polish very smoothly, has made it very valuable as an ornamental wood.

The word "ebony" derives from the Greek εeβεeν?ι?ν?ο?ς? , by way of Latin and Middle English.
