Alton Beast (later known as New Beast) was a roller coaster at Alton Towers. It first opened in 1988 in the Talbot Street (now Cloud Cuckoo Land) section of the park with the Alton Mouse, a second-hand wild mouse coaster, and was marketed by the park as the largest coaster in the UK.

It was a very popular ride, and it stayed in Talbot Street until 1992, when it was moved to Thunder Valley near the Thunder Looper (where the Air shop is now) and renamed the New Beast. In 1994, Nemesis opened and the area was changed into Forbidden Valley. The New Beast stayed in Forbidden Valley until the end of 1997, when it was removed to make way for Air, the park's 2002 flying coaster.It was later removed in 1999
