Ultra Twister was a steel pipeline roller coaster which operated at Six Flags AstroWorld in Houston, Texas, USA. The ride previously operated at Six Flags Great Adventure. It was built by Japanese company Togo. This was also the only Ultratwister to open in North America.

Ultra Twister started construction at Six Flags Great Adventure in November 1985. The ride opened on June 6, 1986.[1] It was located next to Rolling Thunder and featured a chicken exit. The steel rings had a tendency to develop stress fractures that required welding, and the vertical lift made evacuating guests difficult. The ride lasted less than three years and closed in 1988 because of Six Flags' ride rotation program, which saved money. The plot where Ultra Twister stood would be left empty until the construction of Viper, a similar roller coaster had begun in 1994. The ride then opened in 1995.[2] Due to technical issues and maintenance costs, like Shockwave, Ultra Twister was moved to Six Flags AstroWorld. It was repainted and subsequent changes to the ride were made. It reopened in 1990.[3]

Six Flags AstroWorld closed permanently on October 30, 2005.[4] Six Flags relocated rides such as Serial Thriller, a Vekoma SLC, which became Ednör - L'Attaque at La Ronde to be reopened or put in storage at other parks. Ultra Twister was relocated to Six Flags America where it lay in storage for a number of years before being scrapped.
