A backpack was found around 4 p.m. near Space Mountain in the Tomorrowland section of the theme park. That led to an evacuation of that area of the park.
Tomorrowland is home to some of Disneyland's oldest and most popular attractions.
Authorities said all that was found in the backpack was food and park visitors will be let back into the park soon.
Disney is the parent company of ABC30.
