Soledad is a city in Monterey County, California, United States. It is in the Salinas Valley, 21 miles (34 km) southeast of Salinas, the county seat. Soledad's population was 24,925 at the 2020 census, down from 25,738 in 2010. 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 the heavily restored mission, its proximity to Pinnacles National Park, and its numerous vineyards, as part of the Monterey wine region.
