Raspberry Pi OS
A Debian-based distribution for the Raspberry Pi.
Raspberry Pi OS (formerly Raspbian) is the official Linux distribution for the Raspberry Pi single-board computer. It is Debian-based and ships with the Pixel desktop on top of LXDE/LXQt plus a curated set of educational and developer-friendly packages: Thonny, Scratch 3, Mathematica, Wolfram Engine, the Sense HAT emulator, and many libraries for Pi GPIO.
The distribution is maintained directly by the Raspberry Pi Foundation. Releases follow Debian's stable cadence (approximately every two years), with regular intermediate point releases. ARM-32, ARM-64, and "Raspberry Pi OS Lite" (no desktop) variants cover the Pi product line from Pi Zero up to Pi 5.
Raspberry Pi OS is the dominant operating system on Raspberry Pi hardware, with the Raspberry Pi Imager utility making it trivial to flash a microSD card with a configured image (default username, Wi-Fi credentials, SSH key) ready to boot.
