Allen is a city in the province of Río Negro, Argentina. It has 26,083 inhabitants as per the 2001 census [INDEC]. It is located on the left-hand (northern) side of the Alto Valle of the Río Negro, near its beginning in the confluence of the Neuquén and Limay rivers, about 20 km (12 mi) west of General Roca and 35 km (22 mi) east of Neuquén.
Allen was founded on 25 May 1910 by Patricio Piñeiro Sorondo. Its name was an homage to British engineer Charles Allen, a local landowner and member of the Gran Ferrocarril Sur railway company, who managed the construction of the city's train station.
The city is divided in half by a canal born in the Ingeniero Ballester Dam that brings water for irrigation from the Neuquén River. Its main traditional economic activity, which continues to be the most important, is the fruit industry. Allen is the National Capital of the Pear, hosting an annual National Festival of the Pear, and the seat of the Río Negro Fruit Market.

Río Negro (Spanish for "black river") is a river in the Chaco Province in Argentina. It crosses the Chaco National Park and flows southeast. Near its mouth it flows by the cities of Puerto Tirol, Resistencia, and Barranqueras, where it finally reaches Barranqueras River, an arm of the Paraná River.
The river has changed its course over the flatlands several times over the years, leaving wetlands, meanders and lagoons. This took place because of three different factors; frequent droughts, accumulation of sediment, and human-made deviations of the riverbed. Sections of the river are currently contaminated by industrial waste, mainly from the leather tanning industry.
The Río Negro is of historical importance to Resistencia, capital of Chaco Province, since most immigrants that populated Chaco reached the city in boats travelling up-river. On February 2 every year, the Festival of the Canoes and Boats is celebrated, commemorating the day of the arrival of the first steamboat that brought Friulian pioneers to the province.
