羊角拗属（学名：Strophanthus）是夹竹桃科下的一个属，为木质藤本或灌木或乔木植物。该属共有约60种，分布于热带非洲和亚洲。

Strophanthus is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1802. It is native primarily to tropical Africa, extending to South Africa, with a few species in Asia, from southern India to New Guinea and southern China. The name (strophos anthos, "twisted cord flower") derives from the long twisted threadlike segments of the corolla, which in one species (S. preussii) attain a length of 30–35 cm.
