The Galerie Barbazanges was an art gallery in Paris that exhibited contemporary art between 1911 and 1928.
The building was owned by a wealthy fashion designer, Paul Poiret, and the gallery was used for Poiret's "Salon d'Antin" exhibitions. The gallery showed the work of avant-garde artists such as Picasso, Modigliani, Gauguin, Matisse, Chagall, and Dufy.
 In 1911 Henri Barbazanges rented part of the property at 109 Rue du Faubourg Saint Honoré from his friend, the fashion designer Paul Poiret, and opened the Gallery Barbazanges with financial assistance from L. C. Hodebert. The gallery would exhibit contemporary art.
The building was beside Poiret's eighteenth century mansion at 26 Avenue d'Antin.
The Galerie Barbazanges leased the ground floor, with a total area of about 250 square metres (2,700 sq ft).
Behind the front room there were a number of smaller rooms leading to a 70 square metres (750 sq ft) room without windows, but with a glass roof 5.5 metres (18 ft) high.
This large back room may have been built by Barbazanges when he took control in 1911.
A door was made between Poiret's mansion and one of the rooms of the gallery.
 Poiret reserved the right to hold two exhibitions each year. One of these was L'Art Moderne en France from 16–31 July 1916, organized by André Salmon.
Salmon gave "26 Avenue d'Antin" as the address and called the exhibition the "Salon d'Antin". Artists included Pablo Picasso, who showed Les Demoiselles d'Avignon for the first time, Amedeo Modigliani, Moïse Kisling, Manuel Ortiz de Zárate, and Marie Vassilieff.
Poiret also arranged concerts of new music at the gallery, often in combination with exhibitions of new art. 
The 1916 Salon d'Antin included readings of poetry by Max Jacob and Guillaume Apollinaire, and performances of work by Erik Satie, Darius Milhaud, Igor Stravinsky, and Georges Auric.
Satie's Musique d'ameublement (furniture music) was performed in public for the first time at the gallery on 8 March 1920 during intermissions of a play by Max Jacob.
 In 1919 the gallery purchased Paul Gauguin's Self-Portrait with Halo and Snake from François Norgelet. The painting was later acquired by Lord Ivor Charles Spencer Churchill.
 In 1923 Pierre Matisse, son of Henri Matisse and Amélie Parayre, came to work at the gallery to gain experience in the art market before moving to New York in 1924.
In March 1923 Raoul Dufy and Jean Émile Laboureur organized the first Exposition du Groupe des peintres-graveurs indépendents at the gallery. 
A second exhibition of this group was held in 1924.
Another of Poiret's exhibitions, also organized by Salmon, was La Collection particulière de M. Paul Poiret, from 26 April to 12 May 1923.
 Barbazanges retired in 1923, but Hodebert continued to run the gallery under the original name.
Advertisements in 1926 also called it the Galerie Barbazanges-Hodebert.
In the spring of 1928 the gallery moved to 174 Rue du Faubourg St. Honoré, the Galerie Camille Hodebert had been open since 1922.
In 1929 this gallery was called the Galerie L.C. Hodebert.
In January 1929 Hodebart transferred the space of the former Galerie Barbazanges to Georges Bernheim.
It housed the Galerie Heim from the 1950s, which specialized in old master paintings.
