The GE-600 series is a family of 36-bit mainframe computers originating in the 1960s, built by General Electric (GE). When GE left the mainframe business the line was sold to Honeywell, which built similar systems into the 1990s as the division moved to Groupe Bull and then NEC.

The system is perhaps best known as the hardware used by the Dartmouth Time-Sharing System (DTSS) and the Multics operating system. Multics was supported by virtual memory additions made in the GE 645.
