Une semaine de bonté ("A Week of Kindness") is a collage novel and artist's book by Max Ernst, first published in 1934.

The earliest comics by Ernst, Répétitions and Les malheurs des immortels, date from 1922, the year the artist moved to Paris.

The largest and most important before Une semaine de bonté were La femme 100 têtes (1929) and Rêve d'une petite fille qui voulut entrer au carmel (1930).

Une semaine de bonté comprises 182 images created by cutting up and re-organizing illustrations from Victorian novels, encyclopedias, and other books.

They include collages of human bones and plants, one of which was used for the cardboard slipcase that was meant to house all five volumes of Une semaine de bonté.

The book, like its predecessors, has been described as projecting "recurrent themes of sexuality, anti-clericalism and violence, by dislocating the visual significance of the source material to suggest what has been repressed.
