Disney's Typhoon Lagoon is a water theme park located at the Walt Disney World Resort in Lake Buena Vista, Florida near Orlando, and is one of two operating water parks at the resort. It is the second water park to open at the resort, preceded by Disney's River Country which closed in November 2001.

The park, which opened on June 1, 1989, is home to one of the world's largest outdoor wave pools. The theme of the park is the "Disney legend" of a typhoon that wreaked havoc upon a formerly pristine tropical paradise. Ships, fishing gear and surfboards are strewn about where the storm flung them. Its centerpiece is "Miss Tilly," a shrimp boat impaled upon a mountain named "Mount Mayday" that erupts a 50-foot (15 m) geyser of water every half hour, right before the bells of the watch sound on it. Its mascot is “Lagoona Gator."
