Chippewa Operating System (COS)
Developer:	Control Data Corporation
Working State:	Discontinued
Marketing Target:	Supercomputers
Supported Platforms:	CDC 6600 supercomputer
Influenced:	CDC Kronos, CDC SCOPE
License:	Proprietary
Succeeded By:	CDC SCOPE

The Chippewa Operating System (COS) is a discontinued operating system developed by Control Data Corporation in 1964^[1] for the CDC 6600, generally considered the first supercomputer in the world.^[2] The Chippewa was initially developed as an experimental system, but was then also deployed on other CDC 6000 machines.^[3]

The Chippewa was a rather simple job control oriented system derived from the earlier CDC 3000. Its design influenced the later CDC Kronos and SCOPE operating systems.^{[4] [3]} Its name was based on the Chippewa Falls research and development center of CDC in Wisconsin.

It is distinct from and preceded the Cray Operating System (also called "COS") at Cray.
