Henri Célestin Louis Dabadie (1 December 1867, Pau - 19 October 1949, Saint-Mandé) was a French landscape and Orientalist painter.
After completing his studies, he devoted himself to Impressionistic landscape painting; primarily in Brittany.
From 1894, he was a regular exhibitor at the Salon of the Société des Artistes Français.
Thanks to the Société des Peintres Orientalistes Français, he was able to spend a year at the Villa Abd-el-Tif in Algeria, and pay a visit to Tunisia.
That same year, he won the Prix de l'Indochine and settled in Hanoi, where he taught at the Hanoi College of Fine Arts, operated by Victor Tardieu.
