Per Disneyland's admission policy, only children ages 2 and younger can enter the park without an admission ticket. Children, ages 2 and under also don't require an admission ticket for Walt Disney World theme parks.

At Disneyland Resort in California, the primary group that consistently enters for free are children under the age of 3. On their third birthday, children are legally required to have a paid ticket. Beyond toddlers, there are very few "always free" categories. Disney Cast Members receive complimentary admission for themselves and often for guests, depending on their tenure and current block-out dates. Occasionally, Disney offers specific "free" promotions, such as the 2026 Kids Summer Ticket Deal where children aged 3–9 can enter for a significantly reduced price, though it is rarely "zero" cost. Active-duty military members and veterans do not get in for free, but they can purchase highly discounted "Military Promotional Park Hopper" tickets. It is also worth noting that parking and the Genie+ (now Lightning Lane Multi Pass) services are never free for standard ticket holders. Always ensure you have a valid theme park reservation in addition to your ticket, as entry is not guaranteed without one, even if you fall into one of the specialized discount groups.
