Soledad is a city in the Salinas Valley of Monterey County, California. Soledad's population was 25,738 at the 2010 census. Soledad's origins started with Mission Nuestra Señora de la Soledad, founded by the Spanish in 1791, under the leadership of Fermín de Lasuén. Catalina Munrás began developing the town of Soledad on her Rancho San Vicente in the 1860s, which eventually incorporated as a city in 1921. Today, Soledad is a notable tourist destination, owing to its historic mission, its proximity to Pinnacles National Park, and its numerous vineyards, as part of the Monterey wine region.
