Xfce是一个在Unix与Unix-like操作系统，如Linux与FreeBSD上运行的桌面环境。Xfce由许多彼此独立的组件所构成，可以根据用户的需求搭配其他的窗口管理器如Openbox协同运作。Xfce的设计目的是"设计为可作为实际应用，快速加载及运行程序，并减少耗用系统资源"。（Olivier Fourdan，原创者）

Xfce同时为编程者提供开发框架。除了Xfce本身，还有第三方的程序使用Xfce的进程库，如文本编辑器 - Mousepad，多媒体播放程序 - xfmedia与终端机仿真器 - Terminal emulator。

Xfce (pronounced as four individual letters) is a free and open-source desktop environment for Unix and Unix-like platforms, such as Linux, Solaris, and BSD.

Xfce aims to be fast and lightweight, while still being visually appealing and easy to use. Xfce embodies the traditional UNIX philosophy of modularity and re-usability. It consists of separately packaged parts that together provide all functions of the desktop environment, but can be selected in subsets to suit user needs and preference. Another priority of Xfce is adherence to standards, specifically those defined at freedesktop.org.
