Alonso García de Ramón (c. 1552 – August 5, 1610) was a Spanish soldier and twice Royal Governor of Chile: first temporarily from July 1600 to February 1601, and then from March 1605 to August 1610. He was born in Cuenca, Spain in 1552.
He served from the age of 16 in the Spanish Army first against the Morisco revolt in Granada. Then he was in Italy and Sicily, where he was cabo de escuadra, in the squadron of Juan of Austria in the 1572 battle of Navarino following the battle of Lepanto. Then in 1574, he was in the garrison of Goleta during the campaign of Juan of Austria in Tunis. In 1576 he survived under Alvaro de Bazan, Marquess of Santa Cruz in the Battle of Querquenes at the Kerkennah Islands.
He next went to Flanders as a sergeant under Alexander Farnese, Duke of Parma. He was in the assault of the city of Zichem, the attack of Borgerhout and the siege and assault of Maestricht where he was one of the first that mounted the walls; twice wounded taking two flags, for which he was awarded twelve ducados by the Duke.
He returned to Spain and then went to Chile, fighting with skill and bravery for Governor Alonso de Sotomayor against the Mapuche. His most famous action was at the siege of Purén where he killed the Toqui Cadeguala in mounted single combat. Soon after Martín García Óñez de Loyola replaced Sotomayor, García de Ramón moved to Peru, and earned the confidence of the Viceroy of Peru, García Hurtado de Mendoza, 5th Marquis of Cañete who entrusted him with many positions, that he carried out with brilliance including those of corregidor of Arica and Potosí. From 1599, when Francisco de Quiñónez was sent to Chile, he was Maestro de Campo of all Peru and was one of the most trusted military advisors of Viceroy, Luis de Velasco.
