Maynas is one of the eight provinces in the Loreto Region in northeastern Peru. Its capital, Iquitos, is also Loreto's regional capital and the largest city in the Peruvian Amazon Rainforest.

Loreto is Peru's northernmost department and region. Covering almost one-third of Peru's territory, Loreto is by far the nation's largest department, slightly larger than Japan; it is also one of the most sparsely populated regions due to its remote location in the Amazon Rainforest. Its capital is Iquitos.
