Nude Against the Light or Backlit Nude (French: Nu à contre-jour) is an oil-on-canvas painting by the French Post-Impressionist painter Pierre Bonnard, from 1908.

It is now in the collection of the Royal Museums of Fine Arts of Belgium, in Brussels.

[1] The work depicts the artist's partner and frequent model Marthe de Mėrigny applying eau de Cologne after a bath in a tub.

She is nude and standing silhouetted against the windows which fills the room with bright warm shadowless light and colour.

The bather is reflected in a mirror, a characteristic feature of Bonnard's paintings.
