Top Thrill Dragster is a steel accelerator roller coaster built by Intamin at Cedar Point in Sandusky, Ohio, United States. It was the sixteenth roller coaster built at the park since the Blue Streak in 1964. When built in 2003, it was the first full circuit roller coaster to exceed 400 feet (120 m) in height, and was the tallest roller coaster in the world, before being surpassed by Kingda Ka in May 2005.
