José de Santiago Concha y Salvatierra (Lima, Peru, December 1, 1667 – Lima, Peru, March 11, 1741) was a Spanish politician and Royal Governor of Chile.
He studied in Salamanca, and received the title of Knight of the Order of Calatrava due to his noble lineage.
He later served as a magistrate in Lima, later serving in a somewhat similar capacity as an oidor in the Real Audiencia of Chile from 1709 to 1710.
He then returned to Lima to perform his old duties, until the King named him interim governor of Chile.
