A steel roller coaster is a type of roller coaster classified by its steel track, which consists of long steel tubes that are run in pairs, supported by larger steel columns or beams. Trains running along the track typically rely on wheels made of polyurethane or nylon to keep each train car anchored to the track.^[1] The introduction of tubular steel drastically changed roller coaster innovation, allowing for greater speeds, higher drops, and more intense elements such as inversions.

Arrow Dynamics is credited with inventing tubular steel track and introducing the first modern steel coaster with the opening of Matterhorn Bobsleds at Disneyland in 1959. Older steel-tracked coasters existed previously in a simpler form, such as Little Dipper at Memphis Kiddie Park in Brooklyn, Ohio, which is the oldest operating steel coaster in North America. The oldest in the world is Montaña Suiza at Parque de Atracciones Monte Igueldo (Spain), which has been operating since 1928.
