% of the meteorite finds in the Northwest of Africa (Morocco, Mauritania, Mali, and Algeria) were classified under the appellation "NWA" (Northwest Africa) followed by a number. The "NWA" meteorites include rare types that have outstanding scientific significance. The comparison of the temporal evolution of the numbers of meteorite finds in the Northwest region of Africa shows that the adoption of the acronym "NWA," in 2000, has decreased the classification of samples under the proper names of discovery places. Moreover, this denomination has an adverse impact on the meteorite heritage of the countries previously mentioned. In order to enhance this heritage, we have tried to historicize the 5678 meteorite finds "NWA" that were officially published until January 1, 2015. Thus, in addition to the 1180 official "NWA" meteorites whose source country was approved by the Meteorite Nomenclature Committee, we propose to the Committee the re-assignment of 3240 other meteorites to the four countries. Indeed (92%) comes from Morocco, 79 (2.5%) samples from Algeria, 34 (1.1%) from Mauritania and 12 (0.1%) from Mali. Still 1267 remaining "NWA" meteorites do not have information indicating the source country. This reveals that only 23% of NWA meteorites are undocumented while 77% of samples have information on their recovery place. In addition, the proposed nomenclature of meteorites "NWA," following the new Guidelines for meteorite nomenclature, will certainly value the meteorite heritage of the Northwest African countries.
