Disney+ is an American subscription video on-demand over-the-top streaming service owned and operated by the Media and Entertainment Distribution division of The Walt Disney Company. The service primarily distributes films and television series produced by The Walt Disney Studios and Walt Disney Television, with dedicated content hubs for the brands Disney, Pixar, Marvel, Star Wars, and National Geographic, as well as Star in some regions. Original films and television series are also distributed on Disney+.

Disney+ relies on technology developed by Disney Streaming Services, which was originally established as BAMTech in 2015 when it was spun off from MLB Advanced Media (MLBAM). Disney increased its ownership share of BAMTech to a controlling stake in 2017, and subsequently transferred ownership to DTCI, as part of a corporate restructuring in anticipation of Disney's acquisition of 21st Century Fox.Disney+ was launched on November 12, 2019, in the United States, Canada, and the Netherlands, and expanded to Australia, New Zealand, and Puerto Rico a week later. It became available in select European countries in March 2020 and in India in April through Star India's Hotstar streaming service, which was rebranded as Disney+ Hotstar. Additional European countries received the service in September 2020, with the service expanding to Latin America in November 2020. The service expanded to South Africa in May 2022, with other countries in Africa, Western Asia and Europe following suit in June 2022, and other Southeast Asian countries at the end of the year. Upon launch, it was met with positive reception of its content library, but was criticized for technical problems and missing content. Alterations made to films and television shows also attracted media attention. Ten million users had subscribed to Disney+ by the end of its first day of operation.
