Kings Island is a 364-acre (147 ha) amusement park located 24 miles (39 km) northeast of Cincinnati in Mason, Ohio, United States. Owned and operated by Cedar Fair, the park was built by Taft Broadcasting and opened in 1972. It was part of a larger effort to move and expand Coney Island, a popular resort destination along the banks of the Ohio River that was prone to frequent flooding. After more than $300 million in capital investments over the years, the park has grown to feature over a hundred attractions including fourteen roller coasters and a 33-acre (13 ha) water park.
Early in its history, Kings Island appeared in popular sitcoms and received widespread recognition for its record-breaking attractions and events. One of the park's most well-known attractions, The Racer, is often credited with reviving worldwide interest in roller coasters during the 1970s. A variety of attractions over the years introduced notable milestones, and The Beast and Banshee are two that have set enduring world records. The largest single investment in park history is Orion, a $30-million giga coaster that opened in 2020. The park has also experienced a number of setbacks generating negative publicity, including the early demise of The Bat and Son of Beast roller coasters.
Kings Island is divided into eight themed sections and operates seasonally from early spring through Labor Day in the fall, when it transitions to weekend-only operation through Halloween for an annual event called Halloween Haunt. A portion of Kings Island also reopens during the Christmas holiday season for Winterfest. In 2021, Kings Island had an estimated 3.18 million guests, ranking third in attendance among seasonal amusement parks in North America behind sister parks Canada's Wonderland and Cedar Point. In addition, Kings Island has won Golden Ticket Awards in the annual publication from Amusement Today, including "Best Kids' Area" in the world for eighteen consecutive years (2001–2018) and "Best New Ride" in 2017 for Mystic Timbers. In the same publication, The Beast consistently ranks as one of the top ten wooden coasters in the world.
