Viper is a steel roller coaster located in the Baja Ridge area of Six Flags Magic Mountain in Valencia, California.

The track leads into a flat section followed by an s-curve drop and rise into the final brake run, before turning right and returning to the station.

The height record for the tallest vertical loop lasted until 2000, with the opening of Superman: Krypton Coaster at Six Flags Fiesta Texas.

Viper was featured in the 1993 episode of Beverly Hills, 90210, "She Came in Through the Bathroom Window", in which the cast goes to Magic Mountain on Senior Skip Day and Andrea conquers her fear of roller coasters.

In 2012, it appeared in the Glee episode "Big Brother", when the cast rides it during their visit to the park on senior ditch day.

The coaster appears in the video game RollerCoaster Tycoon 2 as part of a recreation of the Six Flags Magic Mountain park.
