Perito Moreno is a town in the northeast of Santa Cruz Province, Argentina, 25 km east of Lake Buenos Aires. It should not be confused with the Perito Moreno National Park over 300 km south by road, or the Perito Moreno Glacier near El Calafate. The town is the capital of the Lago Buenos Aires Department. It lies on the RN43, a paved road which links Caleta Olivia on the Atlantic coast to Los Antiguos and the Chilean frontier 60 km west, and Ruta 40, running north and south.
The town is a centre of cattle ranches and smallholdings producing fruit and vegetables. Tourism is also an important industry. Perito Moreno is the closest town to Cueva de las Manos, 170 km south by road, and Parque Laguna.
In the 2001 census the town had a population of 3,588.
