Facebook Watch (currently rebranding to Facebook Video) is a video on demand service operated by American company Meta Platforms (previously named Facebook, Inc.). The company announced the service in August 2017 and was available to all U.S. users that month. Facebook Watch's original video content is produced for the company by others, who earn 55% of advertising revenue (Facebook keeps the other 45%).

Facebook Watch offers personalized recommendations for videos to watch, as well as categorized content bundles depending on factors such as popularity and social media engagement. Facebook wants both short-form and long-form entertainment on its platform. The company reported a total budget of $1 billion for content through 2018. Facebook monetizes videos through mid-roll advertising breaks and planned to test pre-roll advertising in 2018. On August 30, 2018, Facebook Watch became available to all Facebook users worldwide.

As of September 2020, Facebook reported that Facebook Watch had more than 1.25 billion monthly visitors, 46% of its monthly active user base at that time.
