Nepenthes mirabilis (; from Latin "mirabilis" "wonderful"), or the common swamp pitcher-plant and tropical pitcher plant, is a carnivorous plant species. By far the most widespread of all "Nepenthes", its range covers continental Southeast Asia and all major islands of the Malay Archipelago (minus the Lesser Sunda Islands and northern Philippines), stretching from China in the north to Australia in the south. The species exhibits great variability throughout its range. One of the more notable varieties, "N. mirabilis" var. "echinostoma", is endemic to Brunei and Sarawak and possesses an extremely wide peristome.
