Motif is a graphical user interface (GUI) widget toolkit for Unix-like operating systems using X11. Motif's look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements.

Closely related to Motif is the Motif Window Manager (MWM).

Motif is the toolkit for the Common Desktop Environment (CDE) and thus became the standard widget toolkit for the commercial UNIXes that adopted CDE. CDE was part of the UNIX 98 Workstation Product Standard, so Motif was part of that standard. It was also the toolkit for the IRIX Interactive Desktop.

After many years as proprietary software, Motif was released in 2012, as free software under the GNU Lesser General Public License (LGPL-2.1-or-later).
