Portrait of Marguerite Gauthier-Lathuille or Young Woman in White is a half-length oil on canvas portrait by Édouard Manet, from c. 1878.
It is held in the Musée des Beaux-Arts de Lyon, which acquired it in 1902.
The sitter never posed for the final work, which was instead based on sketches made by the artist.
[1] In the 1870s Manet regularly attended the cabaret run by the subject's father on the avenue de Clichy in the Batignolles quarter of Paris, near the Café Guerbois, a hub for the Impressionists.
In 1879 he showed him in the background of Chez le père Lathuille (Musée des Beaux-Arts de Tournai).
