Gaston Méry (20 April 1866 – 15 July 1909) was a French author, translator and journalist.
He was violently antisemitic and was also hostile to the people of the south of France, whom he saw as racially impure and inferior Latin peoples compared to the Celts of the north.
He founded a journal L'écho du merveilleux which was largely devoted to proving the reality of a series of visions of the Virgin Mary, Joan of Arc and Jesus reported by Marie Martel in Calvados.
From 1900 until his death he was a member of the Paris municipal council.
