Guardians of the Galaxy – Mission: Breakout! is an accelerated drop tower dark ride attraction at the Disney California Adventure park at the Disneyland Resort. Based on the namesake characters from the Marvel Cinematic Universe, it depicts Rocket recruiting guests to attempt to free the remaining Guardians of the Galaxy from display within the Collector's fortress.

A drop tower or big drop is a type of amusement park ride incorporating a central structure or tower. Drop towers vary in height, passenger capacity, lift type, and brake type. Many are custom-made, although there are some mass-produced designs. The most widely sold drop towers have been manufactured by Intamin and S&S Sansei, however Larson International and Funtime have their own drop tower models available as well. Riders initially experience a sense of weightlessness via free fall, followed by rapid deceleration, after which a magnetic brake system brings the ride to a stop. The entire experience generally lasts less than one minute.
