SeaWorld Ohio was a theme park and marine zoological park, located in Aurora, Ohio. It was owned and operated by SeaWorld Parks & Entertainment, formerly known as Busch Entertainment Corporation. The Ohio location was the second SeaWorld park to be built in the chain, following SeaWorld San Diego which opened just six years earlier. The park was developed by George Millay, founder of the SeaWorld brand. Wildwater Kingdom, a waterpark built by Cedar Fair in 2005, occupied the property until its closure in September 2016.
