Joseph Dufour et Cie, founded in 1797 by Joseph and Pierre Dufour, was a French painted wallpaper and fabrics manufacturer located in Mâcon, France.

Wallpaper is used in interior decoration to cover the interior walls of domestic and public buildings. It is usually sold in rolls and is applied onto a wall using wallpaper paste. Wallpapers can come plain as "lining paper" to help cover uneven surfaces and minor wall defects, "textured", plain with a regular repeating pattern design, or with a single non-repeating large design carried over a set of sheets.
