   This is a horrible question. One could argue that the correct answer   
   is "none", since there is no single river, and there considerable   
   stretches of land borders.   
      
   Looking at the map, I've found at least five border rivers. From the   
   north: Minho, Duoro, Tejo, Guadiana, Chança (a tributary to Guadiana),   
   and then Guadiana again.   
      
   The reason I answered Minho is that I recalled that I once stayed a   
   night in Valença do Minho to cross the border to Spain, so that was a   
   river I was sure to be a river that separates Portugal from Spain.   
      
   I know both of the Tejo and Duoro, but they run to the sea in Lisbon   
   and Porto, and I did not know on top of my head if they served as   
   border in some place.
