Adolphe Joseph Reinach (12 January 1887 – 30 August 1914) was a French archaeologist and Egyptologist who participated in excavations in Greece and Egypt and published works on the Gauls.

Adolphe did numerous travels around the Mediterranean and consequently studied at the French School at Athens from 1909 until 1911.

After securing the necessary funds in 1910, he directed the works in Qift with Raymond Weill and André Martinaud, who documented the excavations with numerous photographs.

It is during this time that Adolphe Reinach uncovered the Coptos Decrees dating back to the end of the Old Kingdom and First Intermediate Period.

A lieutenant of Cuirassiers in the 46e régiment d'infanterie in the French Army, he was killed in Fossé in the Ardennes soon after the beginning of the war, at the end of August 1914.
