The IRIS Crimson (code-named Diehard2) is a Silicon Graphics (SGI) computer released in 1992. It is the world's first 64-bit workstation.

Crimson is a member of Silicon Graphics's SGI IRIS 4D series of deskside systems; it is also known as the 4D/510 workstation. It is similar to other SGI IRIS 4D deskside workstations, and can use a wide range of graphics options (up to RealityEngine). It is also available as a file server with no graphics.

This machine makes a brief appearance in the movie Jurassic Park (1993) where Lex uses the machine to navigate the IRIX filesystem in 3D using the application fsn to restore power to the compound.^{[1] [2]} The next year, Silicon Graphics released a rebadged, limited-edition Crimson R4400/VGXT called the Jurassic Classic, with a special logo and SGI co-founder James H. Clark's signature on the drive door.
