A cobra roll is a part of a roller coaster. It is a double-inversion and it looks like the shape of a striking cobra's head. A cobra roll has two half-vertical loops facing the same direction joined together by two half corkscrews that each twist in opposite directions.

A cobra roll is a high-intensity roller coaster inversion that is named for its resemblance to the flared hood of a striking cobra. The element consists of two half-loops and two half-corkscrews joined together. As the train enters the element, it goes through a half-loop into a half-corkscrew, which turns the train upside down and reverses its direction. This is immediately followed by a second half-corkscrew and a second half-loop, which returns the train to an upright position and sends it back in the same direction it entered (or the opposite, depending on the specific design). This "double-inversion" creates significant G-forces and a rapid "head-over-heels" sensation. You can find iconic examples of cobra rolls on coasters like The Incredible Hulk at Universal Islands of Adventure or Alpengeist at Busch Gardens. In 2026, it remains one of the most visually impressive and thrilling elements in coaster design, often used as a "signature" transition in large steel looping coasters.
