Viburnum dentatum, southern arrowwood or arrowwood viburnum or roughish arrowwood, is a small shrub, native to the eastern United States and Canada from Maine south to northern Florida and eastern Texas.

Like most Viburnum, it has opposite, simple leaves and fruit in berry-like drupes. Foliage turns yellow to red in late fall. Localized variations of the species are common over its entire geographic range. Common differences include leaf size and shape and placement of pubescence on leaf undersides and petioles.

Some moth larvae feed on V. dentatum. Known such species include the unsated sallow (or arrowwood sallow; Metaxaglaea inulta) and Phyllonorycter viburnella. It is also consumed by the viburnum leaf beetle (Pyrrhalta viburni), an invasive species from Eurasia. The fruits are a food source for songbirds. Berries contain 41.3% fat.

The fruits appear blue. The major pigments are cyanidin 3-glucoside, cyanidin 3-sambubioside, and cyanidin 3-vicianoside, but the total mixture is very complex.

Native Americans used the young stems to make arrow shafts.
