Storeria dekayi, commonly known as De Kay's brown snake, De Kay's snake, and simply the brown snake (along with many other snakes), is a small non-venomous species of snake in the family Colubridae. The species is native to North America and Central America.

S. dekayi is native to Southern Ontario and Quebec, most of the eastern half of the United States, through Mexico, Guatemala, Honduras, and possibly El Salvador. More specifically, this common species inhabits most wetland and terrestrial habitats east of the Great Plains from sea level to 1,400 meters (4,600 feet) above sea level.
