DesktopBSD is a UNIX-derivative, desktop-oriented operating system based on FreeBSD. Its goal is to combine the stability of FreeBSD with the ease-of-use of KDE, which is the default graphical user interface. It is available for the IA-32 (also known as 32-bit x86) and AMD64 platforms.

DesktopBSD is essentially a customized installation of FreeBSD and is not a fork of FreeBSD. DesktopBSD is always based on FreeBSD's latest stable branch but incorporates certain customized, pre-installed software such as KDE and DesktopBSD utilities and configuration files.

A common misconception about DesktopBSD is that it is intended as a rival to PC-BSD as a BSD-based desktop distribution, since they are similar in structure and goals. However, the DesktopBSD project was started approximately one year before the PC-BSD project, despite the fact that the first PC-BSD release came out before DesktopBSD's. Neither the DesktopBSD nor PC-BSD projects intend to rival each other and are completely independent projects with distinctive features and intended outcomes e.g. DesktopBSD uses ports and packages for additional software installation, whereas PC-BSD introduced PBIs.
