Box, or Boxwood, a genus of evergreen shrubs and trees native to Asia, southern Europe, northern Africa, the West Indies, and Central America. Box is a popular hedge plant in Europe and the United States. The close-grained, light-yellow wood was once used to make woodcuts and is still used to make musical instruments and furniture.

The common box is usually a shrub, but can be a tree that grows up to 25 feet (8 m) tall with a trunk 10 inches (25 cm) in diameter. The shiny, oblong leaves are about one inch (2.5 cm) long. The flowers are inconspicuous. The fruit is a globular, threepointed capsule that splits at maturity into three parts, each containing two shiny black seeds.

The common box is Buxus sempervirens of the family Buxaceae. The Japanese boxwood is B. microphylla.
