William Andrew "Bill" Saturno is an American archaeologist and Mayanist scholar who has made significant contributions toward the study of the pre-Columbian Maya civilization. As of February 2015, Saturno holds a position as assistant professor in Archaeology at Boston University's College of Arts and Sciences. He is also the director of the Proyecto San Bartolo-Xultun at the Instito de Antropologia e Historia in Guatemala, a national space research scientist at the Marshall Space Flight Center, as well as a research associate at the Peabody Museum at Harvard University. Prior to his position at BU, Saturno was a lecturer at the University of New Hampshire.
Saturno is best known for his discovery in 2001 of one of the oldest extant murals in the Maya region, at the site of San Bartolo in northeastern Guatemala. He said this discovery was his favorite and most challenging experience of his career, and that "being the first person to see [the murals] after more than 2,000 years, uncovering them bit by bit, with each part more beautiful than the last, is an experience unlikely to be matched."
