Alfred-Pierre Joseph Agache (French: [alfʁɛd aɡaʃ]; 29 August 1843 – 15 September 1915), also known simply as Alfred Agache, was a French academic painter. Little is known of Agache's life. He was born in Lille, France, and exhibited his work frequently in Paris until his death. He seems to have specialized in portraits and large-scale allegorical paintings. He was a member of the Société des Artistes Français, and won a third-class medal in 1885 for his work.
