CNN+ was a short-lived subscription streaming service and online news channel owned by the CNN division of WarnerMedia News & Sports. It was announced on July 19, 2021 and launched on March 29, 2022. Shortly after its launch, CNN+ closed on April 28, 2022.

CNN+ was designed as an offshoot of the CNN television channel, carrying a daily lineup of live news programming, as well as original series and documentaries drawn from the channel's library, and an "interactive community."

CNN+ was the shortest-lived service under the Warner Bros. Discovery/Turner Broadcasting umbrella, breaking the previous record set by the Cable Music Channel, which lasted 35 days between October 26 and November 30, 1984. During the Warner Bros. Discovery upfronts, it was announced that Who's Talking to Chris Wallace? and the docuseries Eva Longoria: Searching for Mexico, which were announced for the service in December 2021, would both be picked up by the main CNN channel, with the former also premiering episodes on HBO Max.

CNN+ was a failure for a number of reasons. First, it was launched at a time when the streaming market was becoming increasingly saturated. Second, CNN+ did not offer anything that was not already available on other streaming services, such as Netflix, Hulu, and Amazon Prime Video. Third, CNN+ was too expensive. At $9.99 per month, it was more expensive than many other streaming services.
