Markhamia is a genus of flowering trees in the family Bignoniaceae, the trumpet-vine family, within the order Lamiales. The genus comprises a small number of species distributed across tropical Africa and South-East Asia. Members of the genus are typically medium to large trees, characteristic of the Bignoniaceae in bearing showy tubular flowers and long, often pendulous seed pods. Several species, including Markhamia lutea and Markhamia zanzibarica, are familiar components of East African savanna and woodland vegetation, where they are valued for their ornamental flowers and useful timber. The genus was described by Schumann and placed within the tribe Tecomeae of the Bignoniaceae. It is named in honour of Sir Clements Markham (1830–1916), the English geographer and explorer.
