Woody Woodpecker's Nuthouse Coaster, Steel roller coaster in Universal Studios, Florida.

Woody Woodpecker's Nuthouse Coaster was a steel junior coaster at Universal Studios Florida, built between the E.T. Adventure queue and the original Hard Rock Cafe. Its train climbed a lift hill, then ran two drops and several winding turns before a sign reading "Stop! Track ends! Now!" The queue passed Woody's insignia and pullable bells, then a sign where Splinter and Knothead argue over who signs first.

Universal announced the KidZone expansion in May 1998, and Woody Woodpecker's Nuthouse Coaster opened on March 13, 1999, the first roller coaster at Universal Studios Florida and at Universal Orlando Resort. It ran for over two decades before closing on January 15, 2023, and was rethemed into Trolls' Trollercoaster, which opened on June 14, 2024. A version of the design had also been planned for the scrapped Universal Studios Dubailand.

The coaster draws from the classic animated Woody Woodpecker character and his cartoons. Visitors encounter voice recordings and visual elements throughout the ride that echo the original animated series.

The ride closed permanently on January 15, 2023, and was rethemed into Trolls' Trollercoaster, which opened on June 14, 2024. The queue stood between the E.T. Adventure outdoor queue and the original Hard Rock Cafe site, so look for that corner of the park when tracing the old layout.

The queue passed Woody Woodpecker's insignia and pullable bells that made various noises, plus a sign where Splinter and Knothead argued over who would sign first. At the top of the lift, a sign read "Ready or nut...Here we go!" before Woody, voiced by Billy West, said "Guess who?" and laughed.
