The pied tamarin, sometimes referred to as the Brazilian bare-faced tamarin, is a critically endangered species of primate found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Brazil in 2005. The species is endangered due to the increasing size of the city of Manaus which is encroaching on their native habitat.

Manaus is the capital and largest city of the Brazilian state of Amazonas. It is the seventh-largest city in Brazil, with an estimated 2020 population of 2,219,580 distributed over a land area of about 11,401 km2 (4,402 sq mi). Located at the east centre of the state, the city is the centre of the Manaus metropolitan area and the largest metropolitan area in the North Region of Brazil by urban landmass. It is situated near the confluence of the Negro and Amazon rivers. It is one of the two cities in the Amazon Rainforest with a population of over 1 million people, alongside Belém.
