José de Gálvez y Gallardo, 1st Marquess of Sonora was a Spanish lawyer and Visitador general in New Spain (1764–1772); later appointed to the Council of the Indies (1775–1787). He was one of the prime figures behind the Bourbon Reforms. He belonged to an important political family that included his brother Matías de Gálvez and nephew Bernardo de Gálvez.

The Bourbon Reforms consisted of political and economic changes promulgated by the Spanish Crown under various kings of the House of Bourbon, since 1700, mainly in the 18th century. The beginning of the new Crown's power with clear lines of authority to officials contrasted to the complex system of government that evolved under the Habsburg monarchs. For example, the crown pursued state predominance over the Catholic Church, pushed economic reforms, and placed power solely into the hands of civil officials.
