Don Pedro de Rábago y Terán (died 1756) was a Spanish administrator and military officer in New Spain.
In 1754, Don Pedro de Rábago y Terán was sent by the viceroy of New Spain to find a site for an Apache Mission, named a pass between the hills in Menard County overlooking the San Saba River as Puerto de Baluartes (Port of Bulwarks).
[1] As his term as governor of Coahuila expired he was appointed captain of the Presidio del Santísimo Sacramento del Valle de Santa Rosa, where he dealt with problems at the San Xavier missions near present-day Rockdale, Texas that had been exacerbated by his nephew Felipe de Rábago y Terán.
While a jurisdictional question was being debated over whether the mission lay within the boundaries of Texas or Coahuila, the new post remained under the viceroy.
