Yes, you can absolutely bring Starbucks (or any outside food and non-alcoholic beverages) into Disneyland Park and Disney California Adventure in 2026. Disney’s official policy allows guests to bring in outside items as long as they do not require heating, reheating, processing, or refrigeration, and are not in glass containers. This means your plastic or paper Starbucks cup is perfectly fine. It is a common sight to see guests carrying their "Pink Drinks" or Frappuccinos through the security checkpoints in the morning. However, you should be aware that you cannot bring in loose ice; if you have a cooler bag for your drinks, it must be filled with reusable ice packs rather than ice cubes, as part of Disney's safety and cleanliness protocols. Interestingly, if you run out of your outside coffee, both parks feature their own "in-universe" Starbucks locations—Market House on Main Street, U.S.A., and Fiddler, Fifer & Practical Cafe on Buena Vista Street—which serve the full Starbucks menu, though they use Disney-themed branding on the exterior to maintain the "story" of the land.
