An easel is a frame, typically made of wood or metal, that stands upright and is used to hold or support a canvas, painting, chalkboard, or other flat surface, usually at an angle. Artists commonly use easels to hold their canvas while painting or drawing, and easels can also be used to display finished artworks or signs.

The word "easel" originally comes from an old Germanic word for "donkey," reflecting the idea of the easel as a supportive stand, similar to how a donkey carries loads.

There are various types of easels, including those designed for artists' studios, portable field easels for outdoor painting, display easels, and even easels used in photographic darkrooms to hold paper flat during exposures.
