Mahogany is a straight-grained, reddish-brown tropical hardwood prized for its stability, workability, and refined appearance. The term traditionally applies to a small group of closely related trees in the Swietenia genus, native to the Americas, whose timber became one of the most important cabinet woods in European and British furniture making from the seventeenth century onward.

True mahogany is derived from three species: Honduran or Big-leaf Mahogany (Swietenia macrophylla), Cuban or West Indian Mahogany (Swietenia mahagoni), and Swietenia humilis. Of these, Cuban mahogany was historically the most esteemed for fine furniture, while Honduran mahogany became the most widely traded and remains the primary genuine mahogany grown commercially today.

The wood is valued for its fine, even grain, relative freedom from defects, and its ability to be worked, carved, and finished with exceptional ease. Mahogany darkens attractively with age and often displays a subtle chatoyance when polished. These qualities made it central to high-quality furniture, paneling, doors, musical instruments, and boatbuilding during the eighteenth and nineteenth centuries, particularly in Britain, Europe, and North America.

By the late nineteenth century, over-harvesting led to severe depletion of American mahogany forests. As supplies declined, African timbers such as Khaya and Entandrophragma were increasingly sold under descriptive trade names such as African mahogany, while unrelated species were sometimes marketed under the same term. Today, all species of Swietenia are protected under international regulation, and genuine historic mahogany is encountered primarily in antique furniture and restoration work.
