Nepenthes macfarlanei (/nɪˈpɛnθiːz ˌmækfɑːrˈleɪniaɪ/; after John Muirhead Macfarlane, botanist) is a carnivorous pitcher plant species endemic to Peninsular Malaysia.

Upper (aerial) pitchers are of a lighter colour with wings reduced to ribs.

The lower surface of the lid is densely covered with short, white hairs.

This is a characteristic morphological feature of this species, but at present its function is unknown.
