Schlitterbahn is an American brand of water parks and resorts owned by Cedar Fair. It was previously a company family owned and operated by the Henry family that was based in New Braunfels, Texas. Schlitterbahn opened its first location, Schlitterbahn Waterpark Resort, in 1979. At its peak, the company consisted of five outdoor waterparks, two indoor waterparks, and three resorts.

A water park is an amusement park that features water play areas such as swimming pools, water slides, splash pads, water playgrounds, and lazy rivers, as well as areas for floating, bathing, swimming, and other barefoot environments. Modern water parks may also be equipped with some type of artificial surfing or bodyboarding environment, such as a wave pool or flowrider.
