Erythronium dens-canis, the dog's-tooth-violet is a bulbous herbaceous perennial flowering plant in the family Liliaceae. It is native to central and southern Europe from Portugal to Ukraine, and locally naturalised north to Germany, Great Britain, and Ireland. It, and the closely related Erythronium caucasicum in the extreme southeast of Europe, are the only naturally occurring species of Erythronium in Europe. Despite its common name, it is not closely related to the true violets of genus Viola.
