Nueve de Julio is a department of Argentina, located in the south-center of the province of San Juan. Lying within the Tulum Valley agricultural oasis, almost 80% of the department's area is cultivated; it is known in particular for its production of wine and its fruit and vegetable crops.
The earliest inhabitants of the area were the Huarpes, who lived by agriculture, hunting, and fishing in the San Juan River. The Spanish arrived in the area in 1562. The sparsely populated territory became part of the Santa Lucía Department in 1869. As part of a reorganisation within the province in 1913, a municipality of Nueve de Julio was created, which took in the localities of Las Chacritas and Rincón Cercado. Then in 1928 some of the municipalities were abolished, including Nueve de Julio, which was incorporated in Pocito Department. This step was reversed in 1942, when Nueve de Julio became one of the 19 departments of the province, within its present boundaries. Villa Nueve de Julio, Tierra Adentro, Las Majaditas and Las Chacritas are among the districts included within the department. For religious purposes the department fell within the Santa Lucía parish until 1992, when Nuestra Señora del Rosario was chosen as the department's own patron saint.
Nueve de Julio is one of the departments comprising the Tulum Valley, a space enclosed to the east by the San Juan River and to the west by the Agua Negra creek. This valley forms a plain sloping gradually down to the east, comprising oasis areas watered by rivers as well as desert areas which are more predominant in the south of the department. The climate is continental, bringing very hot summers with temperatures up to 40 °C, and cold to moderate winters with sub-zero temperatures.
