Nepenthes merrilliana (/nɪˈpɛnθz mɛˌrɪliˈɑːnə/; after Elmer Drew Merrill) is a tropical pitcher plant endemic to the Philippines. It produces some of the largest pitchers in the genus, rivalling those of N. rajah.[7]

Binomial name
Nepenthes merrilliana

The species is native to northern and central Mindanao as well as neighbouring Dinagat[7] and Samar.[8] Its presence in southern Mindanao is uncertain.[7] It inhabits coastal forest areas on steep slopes[1] at elevations of 0–1100 m above sea level.[9]

Nepenthes surigaoensis is closely related to N. merrilliana and was for a long time considered a heterotypic synonym of this species.[10] Nepenthes samar is another closely allied species.[11]
