The Museu Paraense Emílio Goeldi is a Brazilian research institution and museum located in the city of Belém, state of Pará. It was founded in 1866 by Domingos Soares Ferreira Penna as the Pará Museum of Natural History and Ethnography, and was later named in honor of Swiss naturalist Émil August Goeldi, who reorganized the institution and was its director from 1894 to 1905.
The institution has the mission of researching, cataloging and analyzing the biological and sociocultural diversity of the Amazon Basin, contributing to its cultural memory and its regional development. It has also the aim of increasing public awareness of science in the Amazon by means of its museums, botanical garden, zoological park, etc.
The Museum maintains a scientific research station in the high Amazon forest (Estação Científica Ferreira Penna), which was inaugurated in 1993, with 330 square kilometres (130 sq mi) in the Caxiuanã National Forest, municipality of Melgaço, Pará.
The museum provided assistance in preparing the management plan for the Grão-Pará Ecological Station between 2007 and 2011. This is a strictly protected environmental unit covering 4,245,819 hectares (10,491,650 acres) of Amazon forest created in 2006, the largest such reserve in the world
