Le Déjeuner sur l'herbe (English: Luncheon on the Grass) is an 1865–1866 oil-on-canvas painting by Claude Monet, produced in response to the 1863 work of the same title by Édouard Manet.

It remains unfinished, but two large fragments (central and left panels) are now in the Musée d'Orsay in Paris,[1][2] while a smaller 1866 version is now in the Pushkin Museum in Moscow.

[3] Monet originally wanted to submit the painting to the Salon of 1866, but he underestimated how long it would take him to transfer his sketches to a life-size canvas, so it remained unfinished by the time of the exhibition.

Joel Isaacson believes that, in addition to being influenced by the original Déjeuner, Monet also drew elements from Manet's Music in the Tuileries.

[7]: 32–33  Mary Gedo Matthews believes that in his painting Monet did not hope to pay homage to Manet but instead wanted to demonstrate that his vision was superior.

[10]: 42–43  According to Stephan Koja, Monet's techniques and style were intended to make the scene appear entirely in the present, modern and contemporary, without the use of tradition, in contrast to Manet’s approach.

[12] The Pushkin Museum, however, now states that this version is likely a later repetition of the finished work, based on the careful attention to detail and the presence of the artist's signature.
