San Luis Obispo County, officially the County of San Luis Obispo, is a county located in the U.S. state of California. As of the 2010 census, the population was 269,637. The county seat is San Luis Obispo.

San Luis Obispo County (locally, SLO County) comprises the San Luis Obispo-Paso Robles-Arroyo Grande, CA Metropolitan Statistical Area. The county is located along the Pacific Ocean in Central California, between Los Angeles and the San Francisco Bay Area.

Father Junipero Serra founded the Mission San Luis Obispo de Tolosa in 1772 and the Mission is today an active part of downtown San Luis Obispo (popularly referred to as SLO or SLO-town). The small size of the county's communities, scattered along the beaches, coastal hills, and mountains of the Santa Lucia range, provides a wide variety of coastal and inland hill ecologies to support many kinds of fishing, agriculture, and tourist activities.

The mainstays of the economy are California Polytechnic State University with its almost 20,000 students, tourism, and agriculture. San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa Counties. Wine grapes are the second largest agricultural crop in the county (after strawberries), and the wine production they support creates a direct economic impact and a growing wine country vacation industry.

The town of San Simeon is located at the foot of the ridge where newspaper publisher William Randolph Hearst built the famed Hearst Castle. Other coastal towns (listed from North to South) include Cambria, Cayucos, Morro Bay, and Los Osos -Baywood Park. These cities and villages are located northwest of San Luis Obispo city, and Avila Beach and the Five Cities to the south: Arroyo Grande, Grover Beach, Oceano, Pismo Beach and Halcyon. Nipomo, just south of the Five Cities, borders northern Santa Barbara County. Inland, the cities of Paso Robles, Templeton, and Atascadero lie along the Salinas River, near the Paso Robles wine region. San Luis Obispo lies south of Atascadero and north of the Five Cities region.
