Dinizia excelsa is a South American canopy-emergent tropical rainforest tree species in the family Fabaceae, native to primarily Brazil and Guyana.

[8] It is found in Guyana, Suriname and Amazonia Brazil (in the northern and central-western states of Amapa, Amazonas, Mato Grosso, Para, Rondonia, Roraima and Tocantins).

[12][13][14] On 7 October 2022, a group of researchers after several failed attempts managed to reach the tree and measured a circumference of 9.9 m (32 ft).

The record breaking specimen was found in the 22 million-hectare (54.3 million-acre) Paru State Forest, which is part of an extremely remote area of the southern Guiana Shield.

This means that activities like logging, permitted under the “sustainable use” category when it was previously part of Paru State Park, can no longer be proposed in its bounds.

Scientific research and ecotourism will be allowed in the Giant Trees of the Amazon State Park, which would also generate revenue.
