Mennonites in Paraguay are either Plautdietsch-speakers of mostly Flemish, Frisian and Prussian ancestry or, like the majority of Paraguayans, of mixed or Amerindian ancestry. Ethnic Mennonites contribute heavily to the agricultural and dairy output of Paraguay.

The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland tropical dry broadleaf forest natural region of the Río de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain.
