The Colombia–Peru border is a 1,626 kilometres (1,010 mi) long continuous international border separating the territories of the two South American countries. It was originally established by the Salomón-Lozano Treaty of 24 March 1922 and then by the Río de Janeiro Protocol of 24 May 1934, which ended the Colombia-Peru War. Both agreements establish the border at the Putumayo River, with the exception of the Amazon Trapeze, located between the Putumayo and Amazon rivers, which is under the sovereignty of Colombia.
