The Brazilian pygmy gecko (Chatogekko amazonicus) is a species of South American lizard in the family Sphaerodactylidae. The species is monotypic in the genus Chatogekko.{{cite journal|author=Gamble, Tony|author2=Daza, Juan D.|author3=Colli, Guarino R.|author4=Vitt, Laurie J.|author5=Bauer, Aaron M.|author-link5=:fr:Aaron Matthew Bauer|year=2011|title=A new genus of miniaturized and pug-nosed gecko from South America (Sphaerodactylidae: Gekkota)|journal=Zoological Journal of the Linnean Society|volume=163|issue=4|pages=1244–1266|doi=10.1111/j.1096-3642.2011.00741.x|pmid=22125341|pmc=3223738}} (Chatogekko, new genus). It grows to a maximum total length (including tail) of only {{convert|24|mm|in}}. It is found in leaf litter on the forest floor, and preys on springtails and mites.{{cite book|author1=Pianka, Eric R.|author2=Vitt, Laurie J.|title=Lizards: Windows to the Evolution of Diversity|location=Oakland, California|publisher=University of California Press|year=2006|page=186|isbn=978-0-520-24847-2|url=https://books.google.com/books?id=1h3EpSp-YU4C&pg=PA186}}{{cite book|author1=Zug, George R.|author-link1=:de:George Robert Zug|author2=Vitt, Laurie J.|author3=Caldwell, Janalee P.|title=Herpetology: An Introductory Biology of Amphibians and Reptiles, Second Edition|location=San Diego, California|publisher=Academic Press|year=2001|page=480|isbn=978-0-12-782622-6|url=https://books.google.com/books?id=qdpxsIPm8kkC&pg=PA480}} The species is oviparous.

The gecko's skin is highly hydrophobic, to the degree that Chatogekko amazonicus is able to avoid drowning in rainstorms despite its small size, and even float on water.{{Cite web |title=BBC One - Life, Reptiles and Amphibians, Floating lizard |url=https://www.bbc.co.uk/programmes/p004rqsj |access-date=2022-06-05 |website=BBC |date=22 October 2009 |language=en-GB}}
