Charles-Edmond Duponchel (7 April 1804 – 13 February 1864) was a French military officer accountant, in which capacity he served in Spain and Algeria. In addition, he studied architecture. He has frequently been confused by later writers with his contemporary Henri Duponchel, at one time director of the Paris Opera, who also studied architecture and has often erroneously been referred to under Charles-Edmond Duponchel's name.
