Belterra is a municipal seat and rubber plantation site some 40 km (25 mi) south of the city of Santarém, Brazil (in the federal state of Pará) at the edge of the Planalto at 165 m (541 ft) above sea level.

Belterra was founded as a rubber plantation, after the economic failure of Fordlândia, which had been founded in 1934 by Henry Ford. The intention of the US-Department of Commerce in the 1920s was to produce rubber in Brazil and to import it to USA. The advantage of the Belterra plantation over the plantation of Fordlândia 100 km (62 mi) to the south is the flat topography, which enables the use of machinery. In its peak time in the late 1930s some 50 km (19 sq mi) were cultivated with Hevea Brasiliensis (rubber tree).
