Red Hat Enterprise Linux (RHEL) is a commercial open-source[7][8][9] Linux distribution[10][11] developed by Red Hat for the commercial market. Red Hat Enterprise Linux is released in server versions for x86-64, Power ISA, ARM64, and IBM Z and a desktop version for x86-64. Fedora Linux and CentOS Stream serve as its upstream sources. All of Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform.

The first version of Red Hat Enterprise Linux to bear the name originally came onto the market as "Red Hat Linux Advanced Server". In 2003, Red Hat rebranded Red Hat Linux Advanced Server to "Red Hat Enterprise Linux AS" and added two more variants, Red Hat Enterprise Linux ES and Red Hat Enterprise Linux WS.[12]

Red Hat previously used strict trademark rules to restrict free re-distribution of their officially supported versions of Red Hat Enterprise Linux[13] but still freely provided its source code. Third-party derivatives were able to be built and redistributed by stripping away non-free components like Red Hat's trademarks. Examples include community-supported distributions like Rocky Linux and AlmaLinux, and commercial ones like Oracle Linux. In 2023, Red Hat decided to stop making the source code of Red Hat Enterprise Linux available to the public. The code is still available to Red Hat customers, as well as developers using free accounts, though under conditions that forbid redistribution of the source code.[11]
