Les Tuniques Bleues (Dutch: De Blauwbloezen) is a Belgian series of bandes dessinées (comic books in the Franco-Belgian tradition), first published in Spirou magazine and later collected in albums by Dupuis. Created by artist Louis Salvérius and writer Raoul Cauvin, the series was taken up by artist Lambil after Salverius' death. It follows two United States Army cavalrymen through a series of battles and adventures.
