Geoplana cambara is a species of land planarian belonging to the subfamily Geoplaninae.

[1] It is found in areas of the Atlantic Forest within Saint-Hilaire/Lange National Park in Brazil.

The ventral side is a cream color with black margins.

[2] Along with its coloration, it can be distinguished from other members of Geoplana by a loose muscular tube of parenchymal fibres around the intestine, and a muscular cylinder surrounding the ejaculatory duct with a diameter 12 times that of the duct.

[2] The specific epithet, cambara, is derived from the name of a river flowing near the type locality.
