Orion /ɒrˈaɪˈɪn/ is a steel roller coaster located at Kings Island amusement park in Mason, Ohio.

Manufactured by Bolliger & Mabillard, Orion became the seventh giga coaster in the world when it opened to the public on July 2, 2020.

[4] Cedar Fair also applied for national trademarks for the names Orion and Polaris as a marketing teaser tactic to keep enthusiasts guessing between the two.

[4] On August 15, 2019, Kings Island held an evening event open to both the media and public that officially announced the new coaster as Orion.

[2][3] The announcement also stated that the unofficial X-Base section of the park would be revamped and renamed Area 72 for the 2020 season.

[12] Guests enter the Fort Mason Research Compound by walking through the entrance building, which was originally the Firehawk photo booth.

A blue concrete pylon can be spotted in the area with a stamp that reads Radium XL-200, a reference to Magnum XL-200 at Cedar Point.

On December 30, 2020, it was announced that Orion won the 2020 "Best New Amusement Park Attraction" in the USA TODAY 10Best National Readers' Poll.
