Sistrurus is a genus of pit vipers in the subfamily Crotalinae of the family Viperidae. The genus is endemic to Canada, the United States, and Mexico. Its name comes from the romanized forms of the Greek words for "rattle" (σείστρον, seistron) and "tail" (οὐρά, ora). It shares its root with the ancient Egyptian musical instrument, the sistrum, a type of rattle. Three species are currently recognized.
