Artemisia tripartita is a species of flowering plant in the aster family known by the common name threetip sagebrush.

[1] It is native to western North America from British Columbia to Nevada and Montana to Colorado.

[3] This plant is common and can be dominant in some regions, including the steppe of Washington, the sagebrush of southern Idaho, and the grassland and shrubland in western Montana.

[1] Where their ranges overlaps, this species can be hard to distinguish from Artemisia rigida which also has deeply divided tripartite leaves.

A. tripartita typically has shorter woolly hair on the leaves (long and silky in A. rigida), the leaf parts are usually longer and narrower, and it often grows taller.
