Tizen (/ˈtaɪzɛn/) is a Linux-based mobile operating system backed by the Linux Foundation, developed and used primarily by Samsung Electronics.

The project was originally conceived as an HTML5-based platform for mobile devices to succeed MeeGo. It was backed by other companies under the Tizen Association. Samsung merged its previous Linux-based OS effort, Bada, into Tizen and has since used it primarily on platforms such as wearable devices and smart TVs.

Much of Tizen is open source software, although the software development kit contains proprietary components owned by Samsung, and portions of the OS are licensed under the Flora License, a derivative of the Apache License 2.0 that grants a patent license only to "Tizen-certified platforms".

In May 2021, Google announced that Samsung would partner with the company on integrating Tizen features into Google's Android-derived Wear OS and committed to using it on future wearables, leaving Tizen to be mainly developed for Samsung Smart TVs.^[3]
