The Pastaza (the ancient river Sumatara) is a large tributary to the Amazon River.

The Pastaza river rises on the Ecuadorian tableland, where a branch from the valley of Riobamba unites with one from the Latacunga basin and breaks through the inland range of the Andes; and joined, afterwards, by several important tributaries, finds its way south-east among the gorges; thence it turns southward into the plains, and enters the Amazon in Peru at a point about 60 miles west of the mouth of the Huallaga. So far as known, it is a stream of no value except for canoe navigation. Its rise and fall are rapid and uncertain, and it is shallow and full of sandbanks and snags. Flooding occurs seasonally.

In Ecuador, the Rio Pastaza forms the provincial boundary between the jungle provinces of Pastaza and Morona-Santiago, and also forms part of Ecuador's boundary with Peru.
