Henri Célestin Louis Dabadie was a French landscape and Orientalist painter.

He was a student of Jules-Élie Delaunay and Henri Michel-Lévy. After completing his studies, he devoted himself to Impressionistic landscape painting; primarily in Brittany. He alo painted harbor scenes in Rotterdam and Hamburg.

From 1894, he was a regular exhibitor at the Salon of the Société des Artistes Français. He was awarded a third-class medal in 1895 and a second-class medal in 1901.

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. In 1928, he was named a Knight in the Legion of Honor. 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.
