Steel Force is a steel roller coaster located at Dorney Park & Wildwater Kingdom in Allentown, Pennsylvania. At 5,600 feet (1,700 m) in length, Steel Force is the eighth-longest steel coaster in the world as of 2024.

Built by D. H. Morgan Manufacturing and designed by Steve Okamoto, the roller coaster opened to the public on May 30, 1997, and was billed as "the tallest and longest roller coaster on the east coast", featuring a 205-foot (62 m) drop, 5,600 feet (1,700 m) of track, and a maximum speed of 75 mph (121 km/h).

On September 16, 1996, Dorney Park announced that Steel Force would be added to the park. The ride opened on May 30, 1997.

Steel Force has been ranked among the top steel coasters in the world several times. Its logo was originally intended to be used for the stand-up coaster Mantis (now Rougarou), which opened at Cedar Point a year earlier. Mantis was originally going to be named "Banshee," but the name and logo were changed prior to its debut. Dorney Park adopted it for its Steel Force coaster a year later.

The train departs the station entering a slight decline into the lift hill. After reaching the top, the train enters the first drop of 205 feet (62 m), reaching a maximum vertical angle of 61 degrees. At the bottom of the first drop, riders pass through a tunnel and into a camelback hill. The train then ascends a third hill, which doubles as the entrance to the downward helix turnaround. After the helix, the train enters a mid-course brake run, before entering the ride's finale – a series of three back-to-back airtime hills and a double-up. The first airtime hill in this series features a tunnel, and an on-ride camera snaps photos at the bottom of the second. Following the double-up element, the train passes over the entrance plaza and enters the final brake run before returning to the station.
