"Machaeranthera" is a genus of flowering plants in the daisy family which are known by the common name tansyaster. Tansyasters are variable in appearance. Some are small singular wildflowers while others are sprawling shrubs. Several species easily hybridize with each other as well, making identification difficult. In general, members of the genus may be identified by the sharp-pointed, dagger-shaped anthers in the disc florets at the center of the flower. The flower heads are usually daisylike and are usually a shade of purple or blue, but may be pink, yellow, or white. Tansyasters are native to western North America.

Species include:
*"Machaeranthera arida" - arid tansyaster
*"Machaeranthera asteroides" - fall tansyaster
*"Machaeranthera canescens" - hoary tansyaster
*"Machaeranthera carnosa" - shrubby alkali aster
*"Machaeranthera gracilis" - slender goldenweed
*"Machaeranthera grindelioides" - rayless tansyaster
*"Machaeranthera gypsophila" - gypsum tansyaster
*"Machaeranthera juncea" - rush bristleweed
*"Machaeranthera pinnatifida" - lacy tansyaster
*"Machaeranthera tagetina" - mesa tansyaster
*"Machaeranthera tanacetifolia" - tansyleaf tansyaster
*"Machaeranthera viscida" - sticky tansyaster
