Dón Antonio Gil Ybarbo (1729–1809), also known as Gil Ybarbo, Gil Ibarbo, and many other name variants, was a pioneering settler of Nacogdoches, Texas. Ambiguously described by the National Park Service as a "prolific trader and smuggler," Gil y'Barbo's contribution to Texas was essential to the well-being of "his people," and a critical element in providing a staging point for the Anglo-American settlers that would follow them.
