Corkscrew is a steel roller coaster built by Arrow Development at Cedar Point in Sandusky, Ohio, United States. Built-in 1976, it was the first roller coaster in the world with 3 inversions. The coaster, which features Arrow’s first vertical loop, was built during the same time period as The Great American Revolution at Magic Mountain. However, Revolution opened seven days prior and is therefore credited as the first modern-day coaster to feature a vertical loop.

Corkscrew originally had three 24 passenger trains painted red, white & blue, a color scheme inspired by the U.S. Bicentennial in 1976, the year the ride was introduced. The ride currently operates with two trains to reduce the excessive stacking on the brake run.

Riders are restrained by over-the-shoulder restraints with interlocking seat belts and are required to be 48 inches (120 cm) to ride. As the restraints cannot be unlocked by all cars at once, pedals are hinged on the backs of the cars to be manually released and locked individually by ride operators on the platform.

The ride is 620 m long, consisting of blue tubular steel track with a 1,200 mm separation between tubes, built on 20,000 m2, rides for 1 minute and 40 seconds, and has two 24-passenger trains. Almost daily, a train is transferred off the track once ridership reaches a point that permits two-train operation with little or no waiting in line. A different train is cycled off each day. The ride was designed by Ron Toomer and built by Arrow Dynamics.
