Wicker is hard woven fiber formed into a rigid material, usually used for baskets or furniture. Wicker is often made of material of plant origin, but plastic fibers are also used.

Materials used can be any part of a plant, such as the cores of cane or rattan stalks, or whole thicknesses of plants, as with willow switches. Other popular materials include reed and bamboo.

Often a frame is made of stiffer materials, after which more pliant material is used to fill in the frame. Wicker is light yet sturdy, making it suitable for furniture that will be moved often. It is often used for porch and patio furniture.

Wicker furniture has been documented as far back as ancient Egypt, that was considered to be one of the ideal elements of modern outdoor furniture. It was the first natural material to be used for furniture, starting out as baskets and chairs. The history of wicker furniture was revealed when archaeologists discovered dozens of wicker furniture items made from reed and swamp grasses (Saunders 1990) while working to uncover the civilizations of the Pharaohs.

The popularity of wicker furniture was passed from Egypt to Rome and throughout Europe as international sea traders carried the materials to Great Britain, Portugal, and Spain, and wicker baskets have been found in Pompeii. The popularity of wicker in America, however, was another story as its popularity did not rise until the mid-nineteenth century. It was Cyrus Wakefield who had discovered large quantities of rattan, the most common material for wicker furniture, and began construction of his own line of wicker furniture. That soon caught the attention of the population and made his company one of the leading industries in wicker furniture. It has been proposed that the extensive use of wicker objects in the Iron Age had an influence on the development of the patterns used in Celtic art.^{[citation needed]} In recent times, its aesthetic was influenced heavily by the Arts and Crafts movement at the turn of the 20th century.
