Compaq Computer Corporation was an American personal computer company founded in 1982, and is now a brand name of Hewlett-Packard.

The company was formed by Rod Canion, Jim Harris and Bill Murto — former Texas Instruments senior managers. The name "COMPAQ" was derived from "Compatibility and Quality", as at its formation Compaq produced some of the first IBM PC compatible computers.

Once the largest supplier of personal computing systems in the world[1], Compaq existed as an independent corporation until 2002, when it merged with Hewlett-Packard.
