Wild Mouse, Steel roller coaster at Lagoon Amusement Park in Farmington, Utah.

Wild Mouse is a steel roller coaster at Lagoon Amusement Park in Farmington, Utah, with a track spanning approximately 370 meters and reaching speeds around 45 km/h (28 mph). The ride features multiple tight hairpin turns and seats four riders per car arranged in two rows.

A wooden Wild Mouse opened at Lagoon in 1965, relocated from the Seattle World's Fair, and ran until 1971. In 1973 the ride returned as "The New Wilder Wild Mouse" on the South Midway, likely the same coaster, and operated until 1989. The present steel coaster by Maurer Söhne opened on April 10, 1998, on that same spot; a themed tunnel followed in the 2000 season.

The ride follows the classic Wild Mouse concept with small cars that feel exposed as they navigate tight turns high above the ground. Passengers sit very close together in these tiny vehicles, experiencing each sharp move directly.

The minimum height requirement is 117 cm (46 inches), and the park can process around 900 riders per hour. Expect longer wait times during peak hours, especially on weekends and holidays.

The ride's colour scheme was originally purple and yellow; it was repainted green and yellow for the 2013 season. The cars themselves are painted to look like cats or mice, matching the ride's name.
