Organized in 1807, the parish occupies a portion of south-central Louisiana often included in the cultural region known as Acadiana. As recorded by the 2010 census (census), the parish had a population of 83,384. The parish seat and largest municipality is Opelousas, a historic market town and local center of government and commerce.

Geography and environment

St. Landry Parish lies in a transitional landscape that blends upland prairie, bottomlands and bayou-influenced wetlands. The climate is humid subtropical, with hot summers, mild winters and year-round precipitation that supports agriculture and forested tracts. Rivers, bayous and small lakes shape land use, wildlife habitat and traditional livelihoods.

History and culture

European settlement brought French and Spanish influences, and the parish retains a prominent Catholic and French cultural heritage. St. Landry is known for its Creole and Cajun traditions: French-derived dialects, church-centered community life, and musical forms such as Creole and zydeco contribute to a distinctive regional identity. Local festivals, parish fairs and markets continue to celebrate foodways, music and family histories.

Economy and government

Agriculture has historically formed the economic base, with row crops and livestock adapted to local soils and water regimes; over time manufacturing, services and energy-related activities have also become part of the economy. Local government follows Louisiana's parish system with elected officials responsible for infrastructure, public safety and social services. Opelousas serves as the administrative center and focal point for courts, schools and county-level services.

Transportation and communities

The parish is served by a network of state and U.S. highways, regional rail lines and local roads that link towns, farms and markets. In addition to Opelousas, the parish contains smaller municipalities and rural settlements that provide schools, churches and commercial services for surrounding areas. Community organizations, historical societies and cultural groups document and promote the parish's heritage.
