Hidden Mickey Wiki is a community-driven catalog for Disney fans who enjoy spotting Mickey Mouse shapes and other hidden character details at Disneyland, Disney California Adventure, and the Disneyland Resort in Anaheim. Created to preserve and build on an earlier Hidden Mickeys website, the wiki brings together sightings reported by hunters and organizes them into categories, including confirmed Hidden Mickeys, unconfirmed sightings, other hidden Disney characters, decorative Mickey shapes, wishful thinking, and Mickeys that have been removed.

The site offers attraction and park checklists, a catalog designed for use on mobile devices, and checkboxes to help visitors track what they have found. Its “Disneyland in a Day” checklist lets users mark attractions and record completion times. Fans can contribute by reporting sightings, confirming existing entries, sharing updates, and submitting images through the site’s contact channels. The wiki also includes a Hidden Mickey FAQ and dedicated pages for lost sightings and wishful thinking.
