Lilium lancifolium is an Asian species of lily, native to China, Japan, Korea, and the Russian Far East. It is widely planted as an ornamental because of its showy orange-and-black flowers, and sporadically occurs as a garden escapee in North America, particularly the eastern United States including New England, and has made incursions into some southern states such as Georgia.

Lilium is a genus of herbaceous flowering plants growing from bulbs, all with large and often prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the Northern Hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies.
