Viburnum carlesii (common names arrowwood, Koreanspice viburnum) is a species of flowering plant in the family Adoxaceae (formerly Caprifoliaceae), native to Korea and Japan (Tsushima Island). Growing to 2 m (7 ft) tall and broad, it is a bushy deciduous shrub with oval leaves which are copper-coloured when young. Round clusters of red buds open to strongly scented, pale pink flowers in late spring. These are followed in late summer by oval red fruits ripening to black in autumn. The Latin specific epithet carlesii refers to William Richard Carles (1848–1929), a plant collector in Korea.
