The Valley of Moche, or Valley of Santa Catalina, is a large area of the La Libertad Region in northern Peru surrounding the Moche River. It has been farmed since the pre-Columbian era and currently contains rural and urban settlements. Trujillo is the most important city of the valley. It is now the location of several towns and agricultural areas where products such as sugarcane and asparagus are cultivated. The irrigation of its lands is part of the Chavimochic hydraulic engineering project.
