Hellcat is a wooden roller coaster located at Clementon Park and Splash World in Clementon, New Jersey, United States. The hybrid coaster was built by S&S Power, and opened to the public in 2004. It was first known as Tsunami, but its name was changed to J2 in 2005, which stood for "Jack Rabbit 2", in reference to the park's former Jack Rabbit coaster, which had recently closed. The ride's name was changed for a final time to Hellcat in 2008.
