Solidago ouachitensis is a species of flowering plant in the aster family known by the common name Ouachita Mountains goldenrod. It is endemic to the Ouachita Mountains along the border between Arkansas and Oklahoma in the United States.[1][2]

This species is a perennial herb growing up to about 1.1 meters in height. It produces one or more erect stems from a woody caudex. The serrated leaves are 10 to 13 centimeters long around the middle of the plant and smaller higher on the stem. The inflorescence contains many bell-shaped flower heads. Each flower head usually contains one yellow ray floret and a few disc florets.[3] Flowering occurs in September and October.[2]

This plant is likely a relict of times when conditions were colder and wetter. It only occurs in the cooler, moister sites in the Ouachita Mountains,[2] usually in wet forest habitat on north-facing slopes.[1] Associated species include Magnolia tripetala, Fagus grandifolia, Acer rubrum, Quercus rubra, Aesculus glabra, Asarum canadense, Campanula americana, Panax quinquefolium, Toxicodendron radicans, and Hybanthus concolor.[2]
