Pristimantis jamescameroni is a species of frog belonging to the family Craugastoridae. It is an orange-brown coloured small frog reported so far only from the Aprada-tepui, a table-top mountain in the Bolívar state of Venezuela. It was discovered in June 2012 and formally described in October 2013 by Belgian biologist Philippe J. R. Kok at the Royal Belgian Institute of Natural Sciences and Vrije Universiteit Brussel. The species was named after the Hollywood filmmaker James Cameron, in recognition of his efforts in environmental awareness, and in addition to his public promotion of veganism as a way of animal conservation. Due to its restricted occurrence, the species could be classified as "endangered" according to the criteria of the IUCN Red List of Threatened Species.
