Puerto Arica is a Peruvian town, belonging to the province of Maynas in the Loreto region, on the banks of the Napo River, in northwestern Peru.

During the War of the Pacific, Chilean troops invaded the town, and took it from Peruvian control, after which the Treaty of Ancón was signed, granting a large amount of Peruvian territory to Chile, with Arica becoming a commune of the Department of the same name, within the new Province of Tacna.

[2] After the Salomón–Lozano Treaty, the area was ceded to Colombia, and the original settlers moved south to Maynas Province in eastern Loreto.

Virtually all transport takes place in the Napo river, which connects it to nearby Mazán, Indiana, and Santa Clotilde.

There's also a road that connects it to nearby Flor de Agosto, located 50 minutes away from the town, in the border with Colombia.
