The Ministry of Pensions and National Insurance (MPNI) was a British government ministry responsible for the administration and delivery of welfare benefits. It was headed by the Minister of Pensions and National Insurance. It was created in 1953 as a result of the amalgamation of the Ministry of Pensions and the Ministry of National Insurance. In 1968 a departmental reorganisation saw the Ministry merged with the Ministry of Health to form the Department of Health and Social Security.
