Bal du moulin de la Galette (commonly known as Le moulin de la Galette) is an 1876 painting by French artist Pierre-Auguste Renoir. It is housed at the Musée d'Orsay in Paris and is one of Impressionism's most celebrated masterpieces. The painting depicts a typical Sunday afternoon at Moulin de la Galette in the district of Montmartre in Paris. In the late 19th century, working class Parisians would dress up and spend time there dancing, drinking, and eating galettes into the evening.

Most of the figures featured in Dance at le Moulin de la Galette were Renoir's friends, but he also used a few professional models. Thus, it can be said that the scene he depicts is not a realistic representation of the Moulin's clientele, but rather an organized set of portraits. Like other works of Renoir's early maturity, Bal du moulin de la Galette is a typically Impressionist snapshot of real life. It shows a richness of form, a fluidity of brush stroke, and a flickering light. This portrayal of popular Parisian life, with its innovative style and imposing format, a sign of Renoir's artistic ambition, is one of the masterpieces of early Impressionism.

Renoir delighted in `the people's Paris', of which the Moulin de la Galette near the top of Montmartre was a characteristic place of entertainment, and his picture of the Sunday afternoon dance in its acacia-shaded courtyard is one of his happiest compositions. In still-rural Montmartre, the Moulin, called `de la Galette' from the pancake which was its speciality, had a local clientèle, especially of working girls and their young men together with a sprinkling of artists who, as Renoir did, enjoyed the spectacle and also found unprofessional models. The dapple of light is an Impressionist feature but Renoir after his bout of plein-air landscape at Argenteuil seems especially to have welcomed the opportunity to make human beings, and especially women, the main components of picture. As Manet had done in La Musique aux Tuileries he introduced a number of portraits.

The girl in the striped dress in the middle foreground (as charming of any of Watteau's court ladies) was said to be Estelle, the sister of Renoir's model, Jeanne. Another of Renoir's models, Margot, is seen to the left dancing with the Cuban painter, Cardenas. At the foreground table at the right are the artist's friends, Frank Lamy, Norbert Goeneutte and Georges Rivière who in the short-lived publication L'Impressionniste extolled the Moulin de la Galette as “a page of history, a precious monument of Parisian life depicted with rigorous exactness. Nobody before him had thought of capturing some aspect of daily life in a canvas of such large dimensions.”

Renoir painted two other versions of the subject, a small sketch now in the Ordrupgard Museum, near Copenhagen and a painting smaller than the Louvre version in the John Hay Whitney collection. It is a matter of some doubt whether the latter or the Louvre version was painted on the spot. Rivière refers to a large canvas being transported to the scene though it would seem obvious that so complete a work as the picture in the Louvre would in any case have been finished in the studio.

This painting is doubtless Renoir's most important work of the mid 1870's and was shown at the Impressionist exhibition in 1877. Though some of his friends appear in the picture, Renoir's main aim was to convey the vivacious and joyful atmosphere of this popular dance garden on the Butte Montmartre. The study of the moving crowd, bathed in natural and artificial light, is handled using vibrant, brightly coloured brushstrokes. The somewhat blurred impression of the scene prompted negative reactions from contemporary critics.

Known for his pleasant paintings, Dance at le Moulin de la Galette is regarded as one of the happiest compositions in Renoir's oeuvre. Today, it is on display at the Musee d'Orsay in Paris and is one the most celebrated works in the history of Impressionism. From 1879 to 1894 the painting was in the collection of the French painter Gustave Caillebotte; when he died it became the property of the French Republic as payment for death duties. From 1896 to 1929 the painting hung in the Musée du Luxembourg in Paris. From 1929 it hung in the Musée du Louvre until it was transferred to the Musée d'Orsay in 1986.

The Moulin de la Galette was one of 21 works shown by Renoir at the third Impressionist exhibition in 1877. Every Sunday afternoon young people from the north of Paris contributed in the dance-hall and in the courtyard behind it in fine weather. Most of the figures in Renoir's work with the occasional professional model posing for thin. The scene which Renoir has painted in this work is not an authentic representation of the clientele of the Moulin, but rather a scrupulously organized series of portrait.
