Cygwin/X is an implementation of the X Window System that runs under Microsoft Windows. It is part of the Cygwin project, and is installed using Cygwin's standard setup system. Cygwin/X is free software, licensed under the X11 License.

Cygwin/X was originally based on XFree86, but switched to the X.Org Server due to XFree86 licensing controversy, owing to concerns over XFree86's new software license not being compatible with the GPL.

After a long hiatus following an 8 July 2005 release, the project was revitalised and the developers released a version based on the X.org modular 7.4 release on 12 November 2008 and continue to maintain it.
