Aconitum napellus (monk's-hood, aconite, wolfsbane) is a species of flowering plant in the genus Aconitum of the family Ranunculaceae, native and endemic to western and central Europe.
It is an herbaceous perennial plant growing to tall, with hairless stems and leaves. The leaves are rounded, diameter, palmately divided into five to seven deeply lobed segments. The flowers are dark purple to bluish-purple, narrow oblong helmet-shaped, tall.
Plants native to Asia and North America formerly listed as A. napellus are now regarded as separate species.
