Marc d'Anna (born September 4, 1968), writing under the pen name Alexandre del Valle, is a Franco-Italian writer, professor, columnist, and political commentator. He is known primarily for his analysis of Islamic extremism, and his criticism of Erdoğan's neo-Ottoman, Islamist, and post-Kemalist Turkey. Del Valle is a proponent of the "PanWest paradigm"—the cooperation between the West and Russia against radical Islamism—and coined the concept of "Red-green-brown alliance" in 2002.
