Zydeco Scream, Steel roller coaster in New Orleans, United States.

Zydeco Scream is a Vekoma Boomerang steel roller coaster at Six Flags New Orleans. Its track runs 935 feet (285 m), with a 116.5-foot (35.5 m) lift tower, a cobra roll and a vertical loop. The train runs the course forward and then backward, giving six inversions through three elements.

Zydeco Scream began as Boomerang at Parc de Montjuïc in Barcelona, running from 1990 to 1998 with white track and green supports. Vekoma's Boomerang model was relocated to Jazzland in New Orleans, where it opened on June 10, 2000. After Hurricane Katrina flooded the park on August 29, 2005, the coaster stood but never operated again, and it was demolished in 2024.

The name comes from zydeco, the accordion-and-fiddle dance music of French Creole communities in south Louisiana. The ride opened with Jazzland in 2000, when the park's areas were themed to the state's music and culture. The coaster itself was a standard Vekoma Boomerang, previously run in Barcelona as Boomerang.

The train is divided into seven cars with two rows each, accommodating 28 riders per cycle. The ride processes around 760 passengers hourly, so visiting during quieter periods offers shorter waits.

The structure survived Hurricane Katrina in 2005 but remained inactive for nearly two decades before being dismantled in 2024. This made it a notable symbol of recovery and change in the park following the disaster.
