Martha P. Haynes (b. 1951) is an astronomer at Cornell University who has used radio, infrared, optical, and ultraviolet observations to probe the formation, evolution and content of galaxies and clusters. She has been a leader in the ALFALFA survey and the forthcoming CCAT-prime wide-field submillimeter telescope.
