Amazon Prime Video, also known simply as Prime Video, is an American subscription video on-demand over-the-top streaming and rental service of Amazon offered as a standalone service or as part of Amazon's Prime subscription. The service primarily distributes films and television series produced by Amazon Studios and MGM Holdings or licensed to Amazon, as Amazon Originals, with the service also hosting content from other providers, content add-ons, live sporting events, and video rental and purchasing services.

Operating worldwide, the service may require a full Prime subscription to be accessed. In countries such as the United States, United Kingdom, and Germany, the service can be accessed without a full Prime subscription, whereas in Australia, Canada, France, India, Turkey, and Italy, it can only be accessed through a dedicated website. Prime Video additionally offers a content add-on service in the form of channels, called Amazon Channels, or Prime Video Channels, which allow users to subscribe to additional video subscription services from other content providers within Prime Video.

Launched on September 7, 2006, as Amazon Unbox in the United States, the service grew with an expanding library, and added the Prime Video membership upon the development of the Prime subscription. It was then renamed as Amazon Instant Video on Demand. After acquiring the UK-based streaming and DVD-by-mail service LoveFilm in 2011, Prime Video was added to the Prime subscription in the United Kingdom, Germany and Austria in 2014, available on a monthly subscription of £/€8.99 per month, continuing the plan of LoveFilm Instant. The service was previously available in Norway, Denmark, and Sweden in 2012, but was discontinued in 2013. On April 18, 2016, Amazon split Prime Video from Amazon Prime in the US for $8.99 per month.
