Not surprisingly, N. rajah is a relatively well known plant in Malaysia, especially its native Sabah. The species is often used to promote Sabah, and specifically Kinabalu National Park, as a tourist destination, and features prominently on postcards from the region. Nepenthes rajah has appeared on the covers of several popular Nepenthes publications, including Nepenthes of Mount Kinabalu (Kurata, 1976) and Nepenthes of Borneo (Clarke, 1997), both published in Kota Kinabalu, Malaysia. On April 6, 1996, Malaysia issued a series of four postage stamps depicting some of its more famous Nepenthes species. Two 30¢ stamps, featuring N. macfarlanei and N. sanguinea, as well as two 50¢ stamps, depicting N. lowii and N. rajah, were released. The N. rajah stamp has been assigned a unique identification number in two popular stamp numbering systems: Scott #580 and Yvert #600. Curiously, the peltate leaf attachment that is so characteristic of this species is not shown. Nepenthes rajah was featured in the first episode of Kingdom of Plants 3D, a natural history documentary series presented by David Attenborough.
