Pachysandra terminalis, the Japanese pachysandra, carpet box or Japanese spurge, is a species of flowering plant in the boxwood family Buxaceae, native to Japan, Korea and China and introduced to eastern North America. It is a slow-growing, spreading evergreen perennial growing to 10 cm (4 in) tall by 60 cm (24 in) broad, with alternate, simple, glossy leaves, and creeping stems. The leaves may yellow in direct sunlight or in winter. When growing in a spreading mass of many plants, a dense cover is formed.

The flowers are white, borne above the foliage. In temperate Northern Hemisphere sites they appear late in the month of March and throughout the month of April. The plant is very cold hardy.

The specific epithet terminalis means "ending", and refers to the clusters of leaves which appear at the end of the short stems.
