Édouard Baldus (5 June 1813, Grünebach, Prussia – 1889, Arcueil) was a French landscape, architectural and railway photographer.

In 1851, he was commissioned for the Missions Héliographiques by the Historic Monuments Commission of France to photograph historic buildings, bridges and monuments, many of which were being razed to make way for the grand boulevards of Paris, being carried out under the direction of Napoleon III's prefect Baron Georges-Eugène Haussmann.

The high quality of his work won him government support for a project entitled Les Villes de France Photographiées, an extended series of architectural views in Paris and the provinces designed to feed a resurgent interest in the nation's Roman and medieval past.

In 1856, he set out on a brief assignment to photograph the destruction caused by torrential rains and overflowing rivers in Lyon, Avignon, and Tarascon.

He often retouched his negatives to blank out buildings and trees, or to put clouds in white skies; in his composite print of the medieval cloister of St. Trophime, in Arles (1851), he pieced together fragments of 10 different negatives to capture focus in depth in a panoramic view of the interior space and also render detail in the brightly lit courtyard outside.
