Oecozona neotropica Oecozona neotropica est una ex octo oecozonis quae superficiem Telluris dividunt. Oecoregiones terrestres ambarum Americarum et totam zonam tropicam et temperatam Americae Australis .
Ordo Mundi Naturae Tuendae seu WWF[ 1] duodecim oecoregiones neotropicas definit:[ 2]
Greater Antillean Moist Forests (silvae humidae Antillarum Maiorum )
Talamancan and Isthmian Pacific Forests (silvae Pacificae Talamancae et Isthmi Panamensis )
Chocó-Darién Moist Forests (silvae humidae Chocó et Darién)
Northern Andean Montane Forests (silvae montanae Andium borealium)
Coastal Venezuela Montane Forests (silvae montanae Venetiolae litoralis)
Guianan Moist Forests (silvae humidae Guianarum )
Napo Moist Forests (silvae humidae Napi )
Río Negro-Juruá Moist Forests (silvae humidae fluminum Nigri et Juruá
Guayanan Highlands Forests (silvae montanae Guianarum)
