The 5th Dimension was a dark ride at the Chessington World of Adventures Resort in southwest London, England, when the theme park opened and was the first major special effects attraction of its kind in the UK.

The ride was designed with cars that could stop and rotate to face what was happening in the scene; the same transit system is in use today.

The ride opened in the summer of 1987, designed and produced by Madame Tussauds Studios and originally sponsored by Hitachi.

Upon its initial opening, The 5th Dimension was considered a disappointment by the park management because it did not attract enough attendance.
