Sarcococca (sweet box or Christmas box) is a genus of 11 species of flowering plants in the box family Buxaceae, native to eastern and southeastern Asia and the Himalayas. They are slow-growing, monoecious, evergreen shrubs 1–2 m (3–7 ft) tall. The leaves are borne alternately, 3–12 cm long and 1–4 cm broad.
The genus name Sarcococca comes from the Greek σάρξ (sárx) and κόκκος (kókkos) for "fleshy berry", referring to the black fruit.
