Agustín de Jáuregui y Aldecoa (17 May 1708/1711 – 29 April 1784) was a Spanish politician and soldier who served as governor of Chile (1772–80) and viceroy of Peru (1780–84).

[1] At the age of 25 he entered the military, serving at Cartagena de Indias (now in Colombia) during the British siege in 1740.

Jáuregui was governor of Chile from 6 March 1772 to 1780, during which time he promulgated a number of administrative and governmental reforms.

Individuals could not bear arms in public; theft of animals was to be punished by whipping; shopkeepers who did not close at the proper hour were subject to fines.

With the agreement of Bishop Alday, he restricted the right of asylum in churches to only two, Santa Ana and San Isidro.

Jáuregui presided over the beginning of construction of the cathedral of Santiago, under the direction of the Italian architect he recruited, Gioacchino Toesca.

In 1777 Jáuregui established a militia system to defend against rural banditry and prepare for other military action, although each unit was required to finance uniforms and weapons itself.

Almost before the celebrations in Lima in honour of his arrival had ended, he had to confront the insurrection of Túpac Amaru II (José Gabriel Condorcanqui).

Túpac Amaru II was cacique of Tungasuca, Surimana and Pampamarca, and enjoyed properties, businesses and prestige in the region of Cusco.

He was 40 years old when he led the rebellion, tired of the abuses of the corregidores and merchants and of the reforms of Visitador José Antonio de Areche (customs, taxes, tributes).

However, discontent persisted amongst the native peoples because of abuse of the repartimiento and mita systems of labor tribute, which Jáuregui notified the court of.
