Yes. You can watch Disney Plus content on Fire Stick that runs on Fire OS 5.0 and later. Amazon Fire TV Stick is one of the devices compatible with Disney+ at launch, and there is no such thing as the Disney Plus streaming service not being compatible with Amazon devices. If you don't have a smart TV, Fire Stick is a great option because the Disney Plus app can be installed for free on Amazon Fire TV Stick, allowing you to watch Disney+ on your TV.
