J.D. Edwards is a software company founded in March 1977 in Denver, Colorado by Jack Thompson, Dan Gregory and Ed McVaney. It made its name building accounting software for IBM minicomputers beginning with the System/34 and /36 and focusing from the mid 1980s on System/38 mincomputers, and then the AS/400 when it became available.

The company gradually added functions, its accounting software evolving to become a platform-independent ERP application that was in 1996 renamed OneWorld.

In June 2003, the J.D. Edwards board agreed an offer under which PeopleSoft would acquire J.D. Edwards, and the takeover was completed in July.

The agreement of this offer was followed by attempts from Oracle Corporation to take over the new enlarged PeopleSoft.
