Robert L. Ooley, FAIA is an American architect, author, and preservation advocate based in Santa Barbara, California, known for his long career in public-sector architecture and his work documenting historic architecture in California. A native Californian, Ooley developed an early interest in building and design, eventually pursuing architecture as a profession. His early career was spent in private architectural practice in Santa Barbara before transitioning to public service, where he would spend the majority of his professional life. In 2002, he became County Architect for Santa Barbara County, a role in which he served as the building official and design authority for county projects. Over roughly two decades, he oversaw a wide range of public works, including civic facilities, medical clinics, and emergency service buildings, while also advancing sustainability initiatives in county architecture. Ooley is especially recognized for his leadership in historic preservation, most notably his efforts to secure State and National Historic Landmark status for the Santa Barbara Courthouse and his ongoing work in its conservation. His contributions to preservation and public architecture led to his elevation to the College of Fellows of the American Institute of Architects (FAIA), one of the profession's highest honors.

In addition to his architectural work, Ooley is an active writer and researcher, with a particular focus on California architectural history. He has published and developed several books, including studies on Frank Lloyd Wright and monographs on architects such as Reginald Johnson and George Washington Smith. Throughout his career, Ooley has combined practice, preservation, and scholarship, shaping both the built environment of Santa Barbara and the historical understanding of its architectural legacy.
