Vortex was a steel roller coaster located at Kings Island amusement park in Mason, Ohio, United States.

Designed and manufactured by Arrow Dynamics at a cost of $4 million, the ride officially opened to the public on April 11, 1987.

Vortex occupied the same location in the park once held by The Bat, the world's first suspended roller coaster.

It accommodated more than 46 million guests throughout its lifespan, making Vortex one of the most frequently-ridden attractions in park history.

For the design and construction of the attraction, Kings Island turned to Arrow Dynamics, an industry-leading manufacturer at the time.
