The Steel Dragon 2000 is the longest roller coaster in the world, measuring a whopping 8,133 feet in length. When construction on the coaster finished in August of 2000, it was officially christened the longest in the world, with a Guinness World Record being given to the park for the world's longest track.

In 2026, the title of the longest roller coaster in the world is held by Steel Dragon 2000 at Nagashima Spa Land in Japan, which spans a staggering 8,133 feet (2,479 meters). The ride uses a massive amount of steel to provide earthquake protection, and a single circuit takes over four minutes to complete. However, within the specific category of "dive coasters," a new record-breaker has emerged at Six Flags Over Texas in 2026: Tormenta Rampaging Run. This giga dive coaster, themed around a Spanish bull run, officially holds the world record for the longest dive coaster, measuring 4,199 feet. Beyond traditional amusement park rides, some "mountain coasters" (alpine slides) in Europe and North America can span over 10,000 feet, but in terms of traditional theme park thrill rides, Steel Dragon 2000 remains the global champion for total track length, providing an exceptionally long duration of high-speed hills and turns that few other coasters can match.
