Brookesia nana, also known as the nano-chameleon, is a species of chameleon endemic to montane rainforests in northern Madagascar (North of 16°S).

[3] The species was discovered by herpetologist Frank Glaw and other German researchers in 2021[1] in the rainforest on the Sorata massif in northern Madagascar.

[1][5] This species of chameleon has rows of dorsolateral tubercles along its vertebral column and also has a pelvic spine.

[1] Male chameleons have shorter tails than females which differs from species of the Brookesia minima group.

This species is at higher risk due to low elevation and deforestation, slash-and-burn agriculture, and cattle.
