Alan Hale (March 7, 1958 – June 6, 2026) was an American professional astronomer who co-discovered Comet Hale–Bopp independently of its other co-discoverer, Thomas Bopp, an amateur astronomer. Hale specialized in the study of Sun-like stars and the search for extra-solar planetary systems, and had side interests in the fields of comets and near-Earth asteroids. He was an astronomer most of his life and served as the president of the Earthrise Institute, which he founded, and which has as its mission the use of astronomy as a tool for breaking down international and intercultural barriers. The International Astronomical Union (IAU) named an asteroid in Hale's honor, 4151 Alanhale, in recognition of his numerous comet observations.
