No, Disneyland is not 100 years old yet. As of 2026, Disneyland Park in Anaheim, California, is 70 years old. It officially opened its gates on July 17, 1955. To celebrate this milestone, the resort is hosting "Disneyland After Dark: 70 Years of Favorites" and other commemorative events throughout the year. While the Walt Disney Company itself celebrated its 100th anniversary in 2023 (founded in 1923), the theme park division is younger. Disneyland was the only theme park designed and built to the direct specifications of Walt Disney himself, and it remains the historical heart of the Disney empire. If you're looking for the "Centennial" of the park, you'll have to wait until 2055, but for now, the 70th-anniversary platinum celebrations are the major draw for fans looking to experience seven decades of "Main Street, U.S.A." magic.
