Zadra is a steel roller coaster located at Energylandia in Zator, Poland. It was built and designed by American manufacturer Rocky Mountain Construction (RMC). The ride opened in 2019.^[1] It uses RMC's patented I-Box Track, which consists of a steel track on wooden supports. It is the first coaster to be built from the ground up using the I-Box Track, rather than using an existing structure.^[2] Zadra reaches a height of 62.8 metres (206 ft) making it tie for the tallest RMC steel rollercoaster in the world alongside Iron Gwazi, which has a similar layout. It has a maximum speed of 121 kilometres per hour (75 mph), and features three inversions.^[1]

In December 2018, Zadra's first wooden support structures were erected.^[2] On the night of 10–11 March 2019, part of the unfinished structure was damaged by strong winds. However, this did not affect the ride's planned opening date.^[3] Zadra was supposed to open as a new ride for Energylandia's 2020 season, but opened ahead of schedule on 22 August 2019.^[4]
