Santarém (Portuguese pronunciation: [sɐ̃taˈɾẽj]) is a city and municipality in the western part of the state of Pará in Brazil. Located at the confluence of the Tapajós and Amazon Rivers, it has become a popular tourist destination. It is the second-most important city in the state, and the financial and economic center of the western part of the state. It leads the Santarém Metropolitan Area, made up of Santarém, Belterra and Mojuí dos Campos. It was once home to the Tapajós Indians, a tribe of Native Americans after whom the river was named. They were the leaders of a large, agricultural chiefdom that flourished before the arrival of Europeans.
