Ministry of the Interior and Administration (Polish: Ministerstwo Spraw Wewnętrznych i Administracji) is an administration structure controlling main administration and security branches of the Polish government. After Parliamentary Election on 9 October 2011 was transformed for two ministries: Ministry of Interior (Minister: Jacek Cichocki) and Ministry of Administration and Digitization (Minister: Michał Boni). It was recreated in late 2015. The current Minister of Interior and Administration is Joachim Brudziński.
The ministry was founded in 1918 as the Ministry of Internal Affairs (Ministerstwo Spraw Wewnętrznych). During a reform of the Polish government in 1996 the administration branch was merged into the Ministry and it was renamed to its current name (on 24 December).
While the ministry of the Interior supervises police forces, it does not supervise criminal enquiries; criminal enquiries are conducted under the supervision of the judiciary.
The Ministry's headquarters was located on the Stefan Batory Street, south of Warsaw's city centre and the governmental district which surrounds the Belweder. The Ministry could be referred to by its initials 'MSWiA'.
The last Minister of the Interior and Administration was Jerzy Miller.
