Magnum XL-200, colloquially known as simply Magnum, is a steel roller coaster built by Arrow Dynamics at Cedar Point in Sandusky, Ohio. When it opened in 1989, it was the tallest, fastest, and steepest complete-circuit roller coaster in the world as well as the first hypercoaster – a roller coaster that exceeds 200 feet (61 m) in height. Some have credited Magnum with starting a period in the industry known as the roller coaster wars, in which amusement parks competed with one another at a rapid pace to build the next tallest and fastest roller coaster. More than 40 million people had ridden Magnum as of 2009.Magnum XL-200 held the title of tallest roller coaster in the world until 1994 when The Big One opened at Blackpool Pleasure Beach in the United Kingdom, as well as the title of longest drop and fastest speed until surpassed two years later by Steel Phantom at Kennywood Park outside of Pittsburgh.
Amusement Today presented Magnum with its "Best Steel Roller Coaster" Golden Ticket Award for three consecutive years from 1998 to 2000. As of 2022, it was ranked 25th in the world by the same publication.
