Ingeniero Jacobacci is a city in Río Negro Province, Argentina. It has a population of 5,719 inhabitants and was named in honor of Guido Jacobacci, the director of the railway opened in 1916 between San Antonio Oeste, on the Atlantic Ocean coast, and San Carlos de Bariloche, in the Andes. A remote outpost in windswept Patagonia, Jacobacci benefited from its proximity to scenic Lake Carilaufquen and in 1990, an airstrip was opened to facilitate tourist arrivals in the area.
