Pattalias palustris is a plant species in the family Apocynaceae, also known as Gulf Coast swallow wort. It is native to the southeastern United States from North Carolina to Texas, and to Mexico, Belize, Cuba, the Bahamas, Turks and Caicos Islands, and Cayman Islands.

A perennial vine, it is found in areas of dunes, salt marsh, and coastal hammock within Florida and Alabama.

It was originally known as Cynanchum angustifolium and subsequently known as Seutera angustifolia before it was reclassified as Pattalias palustris by Fishbein in 2017.
