Ronald Shiffman is a Brooklyn-based city planner, architect, professor, and author. He co-founded the Pratt Institute Center for Community and Environmental Development (PICCED), now known as the Pratt Center for Community Development (PCCD) in 1964, which is recognized as the nation's largest public interest architectural, planning, and community development office.

In 1965, he worked with the Central Brooklyn Coordinating Council and Senator Robert F. Kennedy to launch the Bedford Stuyvesant Restoration Corporation, one of the nation's first community development corporations. In the early 1970s, Shiffman, along with members of the American Institute of Architects (AIA), established the Pratt Architectural Collaborative, a public-interest architectural and design service that assisted low- and moderate-income communities.

He is acknowledged as one of the pioneers of the community-based development movement and the community design movement in America. Shiffman was also one of the organizers of the Association of Community Design Centers.
