Pleasanton is a city in Atascosa County, Texas, set about 30 miles south of San Antonio in the gently rolling brush country of South Texas. Established in 1858 and incorporated in 1917, it grew up around the Atascosa River and a 19th-century cattle-ranching economy, and it still calls itself the "Birthplace of the Cowboy" — a nod to the region's early vaqueros and longhorn herds. That heritage shapes the city's identity today, from its western-themed public art to its biggest annual celebration, the Cowboy Homecoming festival and rodeo. The modern economy reaches beyond ranching. Pleasanton sits near the heart of the Eagle Ford Shale, a major oil-and-gas-producing formation that has brought energy-related jobs and services to the area. Agriculture — including cattle, hay, and row crops — remains part of the local picture, and the city serves as a retail and services hub for the surrounding county. Pleasanton suits people who want small-town South Texas living with a reasonable commute into San Antonio. U.S. Highway 281 and State Highway 97 connect the city to Interstate 37, placing San Antonio's employment centers, medical facilities, and international airport within about a 30-to-40-minute drive. Local health care includes Methodist Hospital Atascosa, located a short drive west in the county seat of Jourdanton. Residents describe a friendly, laid-back community built around schools, youth sports, church and civic life, and outdoor recreation along the Atascosa River. The housing stock is a mix of mid-century and later single-family homes on shaded streets, newer subdivisions, and larger rural lots on the edge of town — a blend that gives buyers a range of settings within one small city.
