José de Iturrigaray (in full, José Joaquín Vicente de Iturrigaray y Aróstegui) (1742, Cádiz, Spain – 1815, Madrid) was a Spanish military officer and viceroy of New Spain, from January 4, 1803 to September 16, 1808, during a period of turbulence.
Iturrigaray was born of a family of wealthy Vizcaíno (Basque) merchants in Cádiz. His parents were José Yturrigaray y Gainza, born in Pamplona, Navarre, and María Manuela de Aróstegui y Larrea, born in Aranaz, Navarre.
Under Charles III in 1762 he took part in the Spanish invasion of Portugal and in Gibraltar. In 1793, now under Charles IV, he earned fame for the courage shown in the War of the Pyrenees with Republican France. He was known to be ambitious, and could be predatory. In 1801 he was commander in chief of the army of Andalucía in the so-called War of the Oranges with Portugal, under the command of Generalissimo Manuel de Godoy.
Godoy named him viceroy of New Spain. Iturrigaray arrived in the colony in 1803 with his wife, María Inés de Jáuregui y Aróstegui. She was the daughter of Agustin de Jaúregui y Aldecoa, Viceroy of Peru, born in Lecároz, Valle de Baztán, Navarra, and María Luisa de Aróstegui y Bassave, born in Habana, Cuba, a first cousin of José de Iturrigaray y Aróstegui. When he passed through customs at Veracruz, he brought with him a huge shipment of goods, which entered free of duty because he declared it his personal baggage. The king sent him a large quantity of arms, which the viceroy provided to the regiments of Mexico and Puebla, then stationed in Cuba. Iturrigaray soon gained popularity for his friendly and jovial character, which contrasted with the austere character of his predecessor, Félix Berenguer de Marquina.
