The Guianan savanna (NT0707) is an ecoregion in the south of Venezuela, Guyana and Suriname and the north of Brazil. It is in the Amazon biome. The savanna covers an area of rolling upland plains on the Guiana Shield between the Amazon and Orinoco basins. It includes forested areas, but these are shrinking steadily due to the effect of frequent fires, either accidental or deliberate. The ecoregion includes the Gran Sabana region of Venezuela.

The ecoregion includes three large unconnected areas totaling 10,437,652 hectares (25,792,000 acres). The main section is in southeast Venezuela, the Brazilian state of Roraima and western Guyana. To the southeast a smaller section is in the north of the Brazilian state of Pará extending into the south of Suriname. The most eastern and smallest section is in the Brazilian state of Amapá, stretching north from Macapá. There are small isolated fragments to the north of the main section in the Pakarima foothills in Guyana. The main section includes the Gran Sabana region of Venezuela.

All three sections adjoin the Uatuma-Trombetas moist forests ecoregion to the south. The most eastern section adjoins the Marajó várzea to the east, at the mouth of the Amazon River. The Guianan moist forests ecoregion lies to the east of the main section and to the north of the other two sections. The main section adjoins the Guianan piedmont and lowland moist forests ecoregion to the west. The northern part of the main section adjoins areas of the Guianan Highlands moist forest and Pantepuis ecoregions.
