Coreopsis lanceolata, the Lance-leaved coreopsis, is a North American species of Tickseed in the sunflower family. It is apparently native to the eastern and central parts of the United States and naturalized in Canada, the western United States, Mesoamerica, South America, South Africa, and eastern Asia.

Coreopsis lanceolata is a perennial plant sometimes attaining a height of over 60cm (2 feet). The plant produces yellow flower heads in late summer, each head containing both ray florets and disc florets. The plant is useful for pollinator restoration in large urban cities for providing a food source for wildlife as they tend to drink the nectar and/or eat the seed. The plant should not be over watered as it will flop over. Honeybees and butterflies are attracted to this plant and it may be restricted by growing in containers or in lawns that tend to be mowed.
Introduced to Japan and China as an ornamental species and later used extensively in greenification projects, particularly along river banks and railways, Coreopsis lanceolata is now known to be outcompeting native plant life and has since 2006 been labeled an invasive species by the Invasive Alien Species Act. The cultivation, transplantation, sale, or purchase of Coreopsis lanceolata is now prohibited and the plant has become the subject of a nationwide destruction campaign, even earning a spot on the Ecological Society of Japan's 100 Worst Invasive Species list.
