Religious InstitutionsUnited States51-200 Employees
The Diocese of Sioux City is a Roman Catholic ecclesiastical jurisdiction established in 1902 to serve a multi-county area in northwest Iowa. As part of the ecclesiastical Province of Iowa, it operates under the leadership of a bishop appointed by the Pope and serves as a local church within the broader Catholic community, aligned with neighboring dioceses in Dubuque, Davenport, and Des Moines. The diocese focuses on pastoral care, evangelization, and planning efforts within its territory, including initiatives such as the Ministry 2025 pastoral planning process and a public-facing evangelization campaign to support members who question or struggle with ongoing abuse scandals. Based in the United States, it serves a community with a considerable clergy and lay presence and maintains a defined organizational structure to coordinate religious services, education, and outreach activities. A notable recent development is the assertion of leadership with the appointment of a new bishop in 2006, reflecting ongoing administrative and spiritual guidance for the diocesan mission.
