Lacquerware are objects decoratively covered with lacquer. Lacquerware includes small or large containers, tableware, a variety of small objects carried by people, and larger objects such as furniture and even coffins painted with lacquer. Before lacquering, the surface is sometimes painted with pictures, inlaid with shell and other materials, or carved. The lacquer can be dusted with gold or silver and given further decorative treatments.

East Asian countries have long traditions of lacquer work, going back several thousand years in the cases of Japan, China and Korea. The best known lacquer, an urushiol-based lacquer common in East Asia, is obtained from the dried sap of Toxicodendron vernicifluum. Other types of lacquers are processed from a variety of plants and insects. The traditions of lacquer work in Southeast Asia, South Asia and the Americas are also ancient and originated independently. True lacquer is not made outside Asia, but some imitations, such as Japanning in Europe, or parallel techniques, are often loosely referred to a "lacquer."
