List of heads of government of Northern Ireland

Since 1921, there have been three different prime ministerial offices in Northern Ireland. The most recent devolved cabinet is the Northern Ireland Executive, established under the Good Friday Agreement. The Executive has been in operation, intermittently, since 1999; but had existed continuously since 2007, but after elections following a government collapsed on 16 January 2017, no Executive was formed until January 2020, when the parties came to an agreement and an Executive was subsequently established. The most recent structure, the Office of the First Minister and deputy First Minister, represents a diarchy. As such, there is no longer a singular executive office, but rather a dual office.
