IRIX Interactive Desktop (originally called Indigo Magic) is a desktop environment normally used as the default desktop on Silicon Graphics workstations running IRIX. The IRIX Interactive Desktop uses the Motif widget toolkit on top of the X Window System found on most Unix systems. The default window manager on the IRIX Interactive Desktop is 4Dwm. IRIX Interactive Desktop debuted in September 1993 on the Indy workstation model.

IRIX Interactive Desktop has two primary components: the System Manager and the Toolchest. The System Manager is the main utility for desktop and system configuration. The Toolchest is a menu (normally located on the desktop) that shows which applications are installed on that specific Silicon Graphics workstation. When not in use, program windows minimize onto the desktop in a small square shape with a distinct vector graphic icon (utilizing the IconSmith .fti file format).

The IRIX Interactive Desktop was one of the first default graphical user interface desktops to be standard on a specific Unix computer system.
