Raging Waters Sacramento, Water park in Sacramento, California.

Raging Waters Sacramento was a water park at Cal Expo in Sacramento, California, owned by Palace Entertainment. Its attractions included Dragon's Den, a ProSlide CannonBowl, the Honolulu Half Pipe slide added in 2004, the Cliffhanger and Hurricane Bay slides, the Shark Attack slide complex, Splashdown's two slides ending in a diving board, Breaker Beach wave pool, the Calypso Cooler lazy river, Hooks Lagoon children's water play area and a beach volleyball court.

The park opened in 1986 and became a primary summer recreation destination for the region for multiple decades. The facility ceased operations in 2022 after serving generations of visitors throughout its years of operation.

The park's name tracked its owners: opened as WaterWorld USA in 1986, it became Six Flags Waterworld in 2003, then Raging Waters Sacramento in May 2007 after the Raging Waters brand of Palace Entertainment bought it. Slides carried names such as Dragon's Den, a ProSlide CannonBowl, and Honolulu Half Pipe, added in 2004.

Visitors should prepare for sunny and hot weather by bringing sunscreen and water for hydration. The location was easily accessible by public transportation and offered ample parking for vehicles.

The park's three Premier Parks properties were run on one model, and Premier Parks became Six Flags in 1998 while the Sacramento site kept the WaterWorld USA name until 2003. Six Flags dropped the partnership after the 2006 season; the park was sold in November 2006 and reopened in May 2007 as Raging Waters Sacramento.
