Puerto Nariño is the second municipality of the Amazonas department of Colombia, located on the shore of the Amazon River.

It has about 6,000 residents, most of them are indigenous (from the Ticuna tribe) and its specificity is that it is entirely pedestrian, no car or motorcycle being allowed, as an experiment in an ecological community.

The traffic with the smaller communities along the river, and with Leticia, the only other Colombian municipality in the region, takes place by motorboats.

It is named after a famous Colombian general, Antonio Nariño, who took an active part in the independence war against the Spanish occupiers.

The town was founded on 1961 August 18 by a doctor named Jose Humberto Espejo Hernandez.
