Philip Keyes Yonge (May 27, 1850–August 9, 1934) was a businessman and civic leader. A resident of Pensacola, he was a prominent Floridian. He was a founding member of the Florida Board of Control (the governing body of the State University System of Florida, Florida's public university system) and served on that board for almost 30 years as a member and chairman. The P.K. Yonge Developmental Research School in Gainesville is named for him.
Yonge was designated a Great Floridian by the Florida Department of State in the Great Floridians 2000 Program. A plaque attesting to the honor is located at the Florida Department of Law Enforcement (formerly the P.K. Yonge School), on Palafox Street in Pensacola.
