Gabriel Astruc (14 March 1864 – 7 July 1938) was a French journalist, agent, promoter, theatre manager, theatrical impresario, and playwright whose career connects many of the best-known incidents and personalities of Belle Epoque Paris.

As a regular at Montmartre's prototypically bohemian Le Chat Noir cabaret, he befriended a young Erik Satie and wrote articles and theater pieces under the pen name Surtac.

He also served as booking agent for Feodor Chaliapin, Arthur Rubinstein, and Wanda Landowska, but not Isadora Duncan, whom he considered too subtle to attract a sizable audience.

[3] From 1905 through 1912 Astruc brought a long list of musical giants to Paris under the banner "Great Season of Paris", including an Italian season with Enrico Caruso and Australian soprano Nellie Melba in 1905, the creation of Salome under the baton of Richard Strauss in 1907, the Ballets Russes of Diaghilev in 1909, the Metropolitan Opera conducted by Arturo Toscanini in 1910, and Debussy's Le martyre de Saint Sébastien (text by Gabriele D'Annunzio) in 1911.

After a brilliant and scandalous first season, climaxed by the famous riot at the May 29 premiere of The Rite of Spring, Astruc found himself financially ruined within six months.
