Upper Navarrese (sometimes called High Navarrese) is a dialect of the Basque language spoken in the Navarre (Basque: Nafarroa or Nafarroa Garaia) community of Spain, as established by linguist Louis Lucien Bonaparte in his famous 1869 map. He actually distinguished two dialects: Meridional (area of Pamplona and south) and Septentrional. However, the southern varieties became extinct early in the 20th century.
Koldo Zuazo divides Upper Navarrese into two dialects, Eastern and Western, which are no closer to each other than they are to Gipuzkoan, while the division lines between dialects are fuzzier than the clear-cut lines drawn by the prince Bonaparte.
