Alphonse Giroux

François-Simon-Alphonse Giroux (died May 1, 1848 in Paris) was a French art restorer and ébéniste.

He studied painting under Jacques-Louis David, and founded an art restoration business near the end of the 18th century. He was the official restorer of Notre Dame Cathedral, and collected and exhibited art by Louis Daguerre, Charles Marie Bouton, Charles Arrowsmith, Charles Renoux, and others. As well as restoring art, his business made and sold furniture in various styles for the French royal family and others. He is also known for constructing the daguerrotype cameras designed by Daguerre, the first commercially manufactured photographic camera in the world.

The painter André Giroux was one of his sons.
