Guaiacum (/ˈɡwaɪ.ə.kəm/), sometimes spelled Guajacum, is a genus of flowering plants in the caltrop family Zygophyllaceae. It contains five species of slow-growing shrubs and trees, reaching a height of approximately 20 m (66 ft) but are usually less than half of that. All are native to subtropical and tropical regions of the Americas and are commonly known as lignum-vitae, guayacán (Spanish), or gaïac (French). The genus name originated in Maipurean, the language spoken by the native Taínos of the Bahamas; it was adopted into English in 1533, the first word in that language of American origin.
Members of the genus have a variety of uses, including as lumber, for medicinal purposes, and as ornamentals. The trade of all species of Guaiacum is controlled under CITES Appendix II.
