Indigenous peoples in Guyana, or Native Guyanese, are Guyanese people who are of indigenous ancestry. They comprise approximately 9.16% of Guyana's population. Amerindians are credited with the invention of the canoe, as well as Cassava-based dishes and Guyanese pepperpot, the national dish of Guyana. Amerindian languages have also been incorporated in the lexicon of Guyanese Creole. A lack of writing system at the time of European contact has contributed to a wide array of spellings of group names; an example was the Warao, who had nearly 30 different variants according to early documents.
