  The San Miguel River (Spanish: Río San Miguel) is a river in Colombia and Ecuador. It is a sub-tributary of the Solimões River (middle course of the Amazon) via the Putumayo River.
  
  ## Geography
  
  The San Miguel River rises on the slopes of the Andes Mountains, in the extreme south of the Colombian department of Nariño, on the border between Colombia and Ecuador. It then flows east, marking the border between the two countries, before passing through Ecuador and then joining the Putumayo River, again on the border.
