Storm Runner is a launched roller coaster located at Hersheypark in Hershey, Pennsylvania. Manufactured by Intamin and situated in the Pioneer Frontier section of the park, the Accelerator Coaster opened to the public on May 8, 2004. It reaches a height of 150 feet (46 m) and catapults riders from 0 to 72 mph (116 km/h) in two seconds. Storm Runner features a top hat element, three inversions, a dual loading station, and a magnetic braking system. In addition, it was designed to interact with three other Hersheypark rides: Dry Gulch Railroad, the Monorail, and Trailblazer.

Storm Runner is the first accelerator coaster to utilize over-the-shoulder restraints and the first to have a dual-loading station with switch tracks. It was also the first accelerator coaster to feature inversions; Kanonen at Liseberg was the second. A replica of the ride was included in RollerCoaster Tycoon 3’s Soaked expansion pack under the same name.

In August 2003, Hersheypark announced that it had hired Swiss roller coaster manufacturer Intamin to construct a new launched coaster in the Pioneer Frontier section of the park. The ride would replace Balloon Flite, a children's ride that had operated for 23 years. Hershey Entertainment and Resorts Company was considering one of three names for the coaster: Steel Stampede, Renegade, and Storm Runner. Hershey Entertainment hosted a contest in which members of the public could vote on the name. More than 46,000 people voted on the name over a two-week period. In November 2003, before the name was officially announced, Hershey Entertainment filed a trademark for the name "Storm Runner". Hershey Entertainment formally announced the coaster's name on November 5, 2003. Construction of Storm Runner began in February 2004 and ultimately cost $12.5 million. By April 2004, test runs for the coaster had commenced.

Storm Runner first opened on May 8, 2004. The first people to ride the coaster included members of the Pennsylvania Army National Guard, as well as winners of an online lottery. Initially, the queue line would often be extended with ropes due to the ride's popularity. In 2005, the park added an overflow queue line located next to Trailblazer's first drop.

For the 2020 season, Storm Runner remained closed while waiting on necessary parts for maintenance and repairs that were delayed due to the global COVID-19 pandemic. Storm Runner reopened during the 2021 season.

Storm Runner contains about 2,600 feet (790 m) of track and three inversions. The duration of the ride is about 58 seconds (including the wait on the launch track). The track has near-miss points with three attractions: the Hersheypark monorail, Dry Gulch Railroad, and Trailblazer. As the train leaves the station, it moves through the switch track, and onto the launch track. As the train moves into position, the sound of a heartbeat is heard. After a brief pause, the train rolls backwards slightly, the brakes on the launch track retract, and a pre-recorded voice says "Now, get ready! Here we go!". As the word "go" is heard, the train is launched from 0-72 mph in 1.9 seconds. Part way down the launch track, the riders' photographs are taken.

Immediately following the launch, the train climbs vertically through a 150 ft top hat. The train then drops 180 ft, reaching the top speed of 75 mph, and then climbs into a 135 ft tall cobra loop, a first-of-its-kind element. After another drop, the train traverses yet another first-of-its-kind element, the Flying Snake Dive (a heartline roll followed by a dive drop). Following the final inversion, the train descends and crosses over Spring Creek and a section of Trailblazer, and under a section of the monorail. The train then rises through two banked turns, first to the right, then the left. After a brief moment of air time, the train enters the final brake run. Following the brake run, the train curves to the left, and returns to the side of the station from which it was dispatched.

Storm Runner is an accelerator coaster, in which trains are launched via a hydraulically charged system. Hershey had chosen a hydraulic launch system because it used much less energy compared to a linear induction motor system. At the end of the launch track, there is a small building containing the motors, pumps, and other components of the launch system, including the winch. Within the launch track, there is a catch car running in a trough in the center of the track, which the train connects to for launch. The catch car is connected to the winch with steel cables, two in front of the catch car running parallel down the trough to pull it down the track during launch, and one on the rear to pull the catch car back to the starting point. Prior to launch, hydraulic fluid (a noncompressible fluid) is pumped into several accumulators filled with compressed nitrogen. The additional hydraulic fluid further compresses the nitrogen, which creates energy for the launch. When enough pressure has been achieved and the system is ready for launch, valves open and the pressure built in the accumulators is released, spinning a large winch that pulls the catch car and train rapidly down the track. As the train continues on, the catch car is slowed by its own braking system within the trough, and is slowly returned back to its starting point via electric motors as the system rebuilds pressure for the next launch. A similar system is used on Kingda Ka and Xcelerator, and formerly Top Thrill Dragster.

On June 26, 2018, a 9-year-old boy's harness allegedly was not properly closed after he boarded the train. His father (who was riding with him and properly secured) said his son was scared that he was not properly secured and might be ejected from the ride, claiming his sons restraint was fully open. The ride operators allegedly failed to address the concern when asked for assistance by the father. The man stated the train began to move and his son exited the car, leaving his father to go through the ride. The man stated he and his son have suffered anxiety-like symptoms as a result of the incident, claiming the sound of bus air brakes trigger their anxieties (the ride has several audible pneumatic components). Many have found the claims to be strange as modern attractions often cannot be dispatched if all restraints are not properly closed, much less fully open, and that several ride operators would simply ignore it. A lawsuit was filed two years later on July 2, 2020.
