List of roller coaster rankings

Roller coasters are amusement rides developed for amusement parks and modern theme parks. Early iterations during the 16th and 17th centuries, which were popular in Russia, were wooden sleds that took riders down large slides made from ice. The first roller coasters that attached a train to a wooden track appeared in France in the early 1800s. Although wooden roller coasters are still being produced, steel roller coasters, introduced in the mid-20th-century, became more common and can be found on every continent except Antarctica.

Amusement parks often compete to build the tallest, fastest, and longest rides to attract thrill seekers and boost park attendance. Ranked by height, speed, length, and number of inversions, roller coasters often became the focal point for competing parks. Computer-simulated models led to innovations that produced more intense thrills while improving quality and durability. The debut of Magnum XL-200 in 1989 at Cedar Point introduced the first complete-circuit roller coaster to exceed 200 feet (61 m), marking a pivot point in the industry. The new era, sometimes referred to as the Coaster Wars, saw increasing competition as parks sought to be the latest to break world records, with some only lasting a year or less.

The pace of competition eventually slowed, however. Former record holder Kingda Ka, the previous tallest coaster in the world at 456 feet (139 m), held onto its record from 2005 until its closure in 2024. Other notable coasters include Formula Rossa, the world's fastest, which reaches a top speed of 149 mph (240 km/h), Steel Dragon 2000, the world's longest, measuring 8,133 feet (2,479 m), and The Smiler which features fourteen inversions.
