Porto Inglês salt flats () is a saline wetland in the southwestern part of the island of Maio, Cape Verde, northwest of the city Porto Inglês. It is a protected area (Paisagem Protegida das Salinas do Porto Inglês) and a Ramsar site. It encompasses ecological, landscape, historical and cultural values. The site is frequented by species of birds of conservation interest, some of them protected by national laws and international conventions, and some endemic to the archipelago.
The site supports cream-coloured courser (Cursorius cursor) and the endangered loggerhead sea turtle (Caretta caretta). It hosts characteristic sand dune and wetland birds, including the greater hoopoe-lark (Alaemon alaudipes), the black-crowned sparrow lark (Eremopterix nigriceps), bar-tailed lark (Ammomanes cinctura), the sanderling (Calidris alba) and the bar-tailed godwit (Limosa lapponica). It also has an important population of the Kentish plover: 50% of the total population of Cape Verde (150-300 individuals).
