Based on the world record nomination from the America Records Institute (AMRI) and Decision No. WK/USA.INDIA1388/2025/No.842, the World Records Union (WorldKings) officially declared Mount Roraima as the world’s highest table-top mountain.

Mount Roraima is the highest of the Pacaraima chain of tepuis (table-top mountain) or plateaux in South America. It is located at the intersection of Brazil, Guyana, and Venezuela. The highest point of Mount Roraima is located on the southern edge of the cliff at an elevation of 2,810 m (9,220 ft) in Venezuela. 

The name Mount Roraima came from the native Pemon people. "Roroi" in the Pemon language means "blue-green," and ma means "great." Due to the late exploration of this part of South America and the discovery of new species every year, the flora and fauna here are largely unknown. 

Not only is Mount Roraima geologically distinctive, but it also features a remarkably unique ecosystem. Isolated from the surrounding environment for 70 to 90 million years, the mountaintop ecosystem has been described as a "lost world," where flora and fauna have evolved in distinctive ways without influence from mainland species.

Approximately one-third of the flora in this region is endemic, indicating that it is exclusive to the tepui and does not occur elsewhere in the world. Certain carnivorous plants and distinctive orchids have successfully adapted to the challenging conditions prevailing on the mountaintop.
