The Minister for Posts and Telegraphs (Irish: Aire Puist agus Telegrafa; sometimes called the P&T or stylised the P+T) was a senior post in the government of the Irish Free State and Ireland from 1924 to 1984, when the post and the department was abolished.

The office of Minister for Posts and Telegraphs was created in the Ministers and Secretaries Act, 1924, which reorganised the Irish system of government. It assumed the role in the Irish Free State of that formerly exercised by the Postmaster General of the United Kingdom. Legislation of 1831 had amalgamated the offices of Postmaster General of Great Britain and Postmasters General of Ireland, a jointly held role in the administration of the Lord Lieutenant of Ireland.

This later and final version of the logo of the department was most commonly associated with the orange and white postal vans.

The Ministers and Secretaries Act, Section (1), Part (ix) defines the department's role:

The Department of Posts and Telegraphs which shall comprise the administration and business generally of public services in connection with posts, telegraphs, and telephones, and all powers, duties and functions connected with the same, and shall include in particular the business, powers, duties and functions of the branches and officers of the public services specified in the Eighth Part of the Schedule to this Act, and of which Department the head shall be, and shall be styled, an t-Aire Puist agus Telegrafa or (in English) the Minister for Posts and Telegraphs.

The Minister for Posts and Telegraphs was responsible for Ireland's postal and telecommunications services from 1924 to 1984. At its height time the department was one of the largest civil service departments in Ireland. The reform of the sector and department began in 1978 with the creation of the Posts and Telegraphs Review Group. This led after a report was delivered in 1979, to the creation of the ad-hoc Interim Board for Posts (An Bord Poist), chaired by Feargal Quinn, and the Interim Board for Telecommunications (An Bord Telecom), chaired by Michael Smurfit. These two boards continued to sit until An Post and Telecom Éireann, respectively, replaced them. These state-sponsored bodies were created in 1984.

The Minister of Posts and Telegraphs ceased to exist at that time, and its powers and responsibilities were transferred to the newly created office of Minister for Communications; this was one of the largest reorganisations of the civil service in modern times with it having a workforce of about 30,000 prior to dissolution. As a result, the number of civil service employees nearly halved overnight because of the transfer of personnel.
