David Arthur Duffield (born 21 September 1940) is an American billionaire businessman in the software industry. He is the co-founder and former chairman of PeopleSoft, and co-founder and CEO emeritus of Workday, Inc.. In addition, he is founder and co-CEO of Ridgeline, Inc.

Duffield has donated more than $500 million to his alma mater Cornell University, including a series of donations in the 2020s totaling over $400 million. As a result, the university renamed its College of Engineering after him. He has also given $303 million to companion animal welfare causes and organizations, over $100 million to expand other educational institutions close to him and his family, $13 million to local first responders and community organizations, and $2.1 million to veterans affairs. His philanthropic interests are managed by the Dave & Cheryl Duffield Foundation. One of their main projects is the planned Liberty Dogs, a 27-acre service dog training campus in Reno, Nevada, that will match and train disabled military veterans and canine companions.
