Philippe Victor Diolé (Saint-Maur-des-Fossés, August 24, 1908 – Paris, November 12, 1977) was a French author and undersea explorer.

Diolé was born in Saint-Maur-des-Fossés, Val-de-Marne,^[1] France, son of Marcel (a jurist) and Elizabeth (Legrand) Diolé. He received a Licence en Droit (a law degree) from the University of Paris in 1928. He married Marguerite Monsenergue on July 6, 1953.

With Jacques-Yves Cousteau he co-authored 7 of the 8-volume series The Undersea Discoveries of Jacques-Yves Cousteau (1970-1975) and co-authored The Whale (1987), which was released posthumously.

In 1977, shortly before his death, Philippe Diolé was co-founder in Paris of the LFDA foundation (fr: La Fondation Droit Animal), aimed to defend animal rights.^[2]
