Nepenthes argentii (pronounced /nəˈpɛnθiːz ɑːrɡˈɛntiːaɪ/ or /ɑːɹdʒˈɛntiːaɪ/, after George Argent) is a highland Nepenthes pitcher plant native to Mount Guiting-Guiting on Sibuyan Island in the Philippines. It is possibly the smallest species in the genus and does not appear to have a climbing stage.[1]

N. argentii inhabits subalpine shrubbery "with a smooth wind-clipped canopy 30 cm tall on an ultrabasic ridge".[2] It grows at an elevation of approximately 1,400 m.[2]

N. argentii has no known natural hybrids. No forms or varieties have been described.

On Mount Guiting-Guiting, N. argentii is sympatric with N. sibuyanensis at around 1800 m.[3][1] A species resembling N. alata grows on Mount Guiting-Guiting at lower elevations of 800 to 1000 m.[4] Other plant species endemic to the mountain include Lobelia proctorii[5] and Rhododendron rousei.[6]
