Amalocalyx is a genus of plant in family Apocynaceae consisting of lianas often found clinging to trees. It was first described as a genus in 1898.

Three species names have been created in the genus. Some authors recognize all three as distinct species, but the World Checklist maintained by Kew Royal Botanic Garden considers the genus as constituting a single species, Amalocalyx microlobus.

These lianas are found in altitude ranges of in Southern Yunnan (South-east China), Laos, Cambodia, Burma, Thailand, Vietnam, and western Malaysia.
