Pierre Trémaux (20 July 1818 – 12 March 1895) was a French architect, Orientalist photographer and author of numerous scientific and ethnographic publications.

Interested in natural history, he traveled to Algeria, Tunisia, Upper Egypt, Sudan and Ethiopia in 1847–1848, where he made many drawings and was one of the first persons to produce photographic images of these regions.

"[3] Nevertheless, his published works, such as the Voyages series of 1852 to 1862, were the first books on Egypt, Sudan, Palestine and other Middle Eastern regions with illustrations based on photographs by the author.

[5] Between 1852 and 1868, Trémaux produced a number of distinct groups of photographic plates to accompany texts on the geography, architecture, and people of regions in Africa and Asia Minor.

Produced with the support of the French government, these high quality publications combined an array of graphic techniques in ways that had not previously been attempted.
