Finlaysonia is a genus of flowering plants in the dogbane family Apocynaceae, found from Sri Lanka, India, through Southeast Asia, New Guinea, northern Australia, the Philippines, and Palau. They tend to be vines or climbers and prefer to live on limestone, alongside rivers, or in mangrove swamps.{{cite book |date= 28 March 2019|title= Flowering Plants.
