Rosa acicularis, also known as the prickly wild rose, the prickly rose, the bristly rose and the Arctic rose, is a species of wild rose with a Holarctic  distribution in northern regions of Asia, Europe, and North America. It is a deciduous shrub growing to 1–3 m tall. The leaves are pinnate, 7–14 cm long, with three to seven leaflets.They are compound, ovate, and the margins are wavy. The flowers are pink (rarely white), 3.5–5 cm diameter; the hips are red, pear-shaped to ovoid, 10–15 mm diameter. It is the provincial flower of the Canadian province of Alberta, and is located throughout the province and Western Canada.

The Prickly Wild Rose could be confused with the Common Wild Rose, also called Wood Rose, but the upper stems of that species lack the many small bristles and prickles that cover the stems of the Prickly Wild Rose. Instead, the Common Wild Rose has a few scattered thorns, usually at stem nodes. It is found infrequently across the boreal forest from southern Manitoba to eastern Alaska. Despite its name, the Common Wild Rose is by far the less common of the two species in our region. The ploidy of this species is variable. Authorities list it as tetraploid, hexaploid and octoploid. On the northern Great Plains its populations are generally tetraploid.

The fruit of the Prickly Wild Rose has a high vitamin C content and makes excellent jelly. Also, rose hips are gathered for the preparation of rose hip tea.
