Chimonanthus praecox, also known as wintersweet or Japanese allspice, is a species of flowering plant in the genus Chimonanthus of the family Calycanthaceae, native to China. The Chinese name is 蜡梅.

It is a vigorous deciduous shrub growing to 4 m (13 ft) tall with an erect trunk and leaves 5–29 cm (2–11 in) long and 2–12 cm (1–5 in) broad. Its strongly scented pendent flowers, produced in winter on bare stems, have 15-21 yellow tepals, the inner ones usually with purplish red pigments.[4][5][6]

This plant is cultivated in gardens, producing valued flower colour in the dormant season. The varieties C. praecox 'Grandiflorus'[7] and C. praecox 'Luteus'[8] have gained the Royal Horticultural Society's Award of Garden Merit.
