Émile Eugène Louis Hamonic (1861–1943) was a French photographer and publisher, associated with the picture-postcard boom of the early 20th century.
He established himself as a publisher of picture postcards in Saint-Brieuc in 1893, becoming one of the first great editors of this genre.
His cards typically presented idealised images of his native Brittany.
He was also a committed supporter of Breton regionalism, and was an active member of the Breton Regionalist Union.
