The Ministry of Social Affairs and Housing is a cabinet-level government department in Iceland responsible for social security, public housing policy, family welfare, and community services. Tracing its origins to the establishment of Iceland's Ministry of Social Affairs in 1939, the institution played a central role in constructing the country's modern welfare system. Over the decades, its administrative structure underwent multiple reorganizations, including merging into the Ministry of Welfare in 2011 before re-emerging with an explicit portfolio focus on housing and social protection.
