The Big One, formerly known as the Pepsi Max Big One, is a steel roller coaster located at Pleasure Beach Resort in Blackpool, Lancashire, England.

It held the title as the tallest until 1996 when Fujiyama opened in Japan. Construction of the ride cost £12 million. The ride was sponsored by Pepsi until 2011, at which time Pepsi Max was removed from the name.
