Viola trinervata, the sagebrush violet, is a species of wildflower in the Violaceae family which is found in eastern Washington and Oregon.

[1] Sagebrush violet is a low growing perennial herb that produces a cluster of palmate leathery leaves with prominent veins.

The showy flowers form in the spring and arise singly from basal stems.

[3] The sagebrush violet grows in seasonally moist big sagebrush habitat and nearby rocky hillsides on the Columbia River plateau in Washington and Oregon states at elevations of 400 to 1200 meters.

The sagebrush violet seeds have a fleshy elaiosome, suggesting that they are dispersed in part by ants.
