Heliamphora chimantensis is a species of marsh pitcher plant endemic to the Chimantá Massif in Venezuela. Specifically, it has been recorded from Apacará and Chimantá Tepuis. It is thought to be more closely related to the southern growing H. tatei and H. neblinae than to any of the other species found in the Gran Sabana and its tepuis. All other species known from this region have between 10 and 15 anthers, while H. tatei, H. neblinae and H. chimantensis have around 20. However, the anthers of H. tatei and the closely related H. neblinae (once thought to be a variety of the former) are 7-9 mm long, while those of H. chimantensis only reach 5 mm in length.
