The Tower of Terror II was a steel shuttle roller coaster located at the Dreamworld amusement park on the Gold Coast, Queensland, Australia. When the Tower of Terror opened on 23 January 1997, it was the first roller coaster in the world to reach 100 miles per hour (160 km/h), making it the tallest and fastest roller coaster in the world of its time. The ride was situated on the Dreamworld Tower, which also houses The Giant Drop free fall ride. The ride was originally known as the Tower of Terror until it was modified and relaunched in September 2010 as Tower of Terror II.

The steel and concrete structure cost A$16 million to construct. The original ride featured a shorter, 80-metre (260 ft) tunnel, a rigid lap bar using a hydraulic locking system, and would carry 15 passengers at a time.

The relaunched ride takes 14 passengers. It propels passengers to just under 161 kilometres per hour (100 mph) with a maximum of 4.5 g and 6.5 seconds of weightlessness. As of 2010, the ride was 4th in the tallest roller coaster rankings, 3rd in the tallest roller coaster drop rankings and 4th in the fastest roller coaster rankings.

On 24 October 2019, the park announced that the Tower of Terror II would close on 3 November the same year, to make room for future development and expansion to the park. The park also confirmed that The Giant Drop will continue to operate as normal, with the Tower of Terror II track being removed from the Dreamworld Tower structure over time.
