Sphaeromeria simplex is a species of flowering plant in the aster family known by the common names Laramie chickensage[1] and Laramie false sagebrush. It is endemic to Wyoming in the United States.[2][3]

This small perennial herb forms clumps a few centimeters tall. The leaves are divided into many lobes. The flower heads contain many yellow disc florets and no ray florets. Flowering occurs in May through August.[4]

This plant grows on exposed limestone substrates among other cushionlike plants and some larger plants such as sagebrush.[3] There are 11 occurrences of the plant, most of which have been discovered since 1997.[2]
