The Continuity Irish Republican Army (Continuity IRA or CIRA), styling itself as the Irish Republican Army (Irish: Óglaigh na hÉireann), is an Irish republican paramilitary group that aims to bring about a united Ireland. It claims to be a direct continuation of the original Irish Republican Army and the national army of the Irish Republic that was proclaimed in 1916. It emerged from a split in the Provisional IRA in 1986 but did not become active until the Provisional IRA ceasefire of 1994. It is an illegal organisation in the Republic of Ireland and is designated a terrorist organisation in the United Kingdom, New Zealand and the United States. It has links with the political party Republican Sinn Féin (RSF).

Since 1994, the CIRA has waged a campaign in Northern Ireland against the British Army and the Police Service of Northern Ireland (PSNI), formerly the Royal Ulster Constabulary. This is part of a wider campaign against the British security forces by dissident republican paramilitaries. It has targeted the security forces in gun attacks and bombings, as well as with grenades, mortars and rockets. The CIRA has also carried out bombings with the goal of causing economic harm and/or disruption, as well as many punishment attacks on alleged criminals.

To date, it has been responsible for the death of one PSNI officer. The CIRA is smaller and less active than the Real IRA, and there have been a number of splits within the organisation since the mid-2000s.

In fiction, continuity is a consistency of the characteristics of people, plot, objects, and places seen by the reader or viewer over some period of time. It is relevant to several media.

Continuity is particularly a concern in the production of film and television due to the difficulty of rectifying an error in continuity after shooting has wrapped. It also applies to other art forms, including novels, comics, and video games, though usually on a smaller scale. It also applies to fiction used by persons, corporations, and governments in the public eye.

Most productions have a script supervisor on hand whose job is to pay attention to and attempt to maintain continuity across the chaotic and typically non-linear production shoot. This takes the form of a large amount of paperwork, photographs, and attention to and memory of large quantities of detail, some of which is sometimes assembled into the story bible for the production. It usually regards factors both within the scene and the technical details, including meticulous records of camera positioning and equipment settings. The use of a Polaroid camera was standard but has since been replaced by digital cameras. All of this is done so that, ideally, all related shots can match, despite perhaps parts being shot thousands of miles and several months apart. It is an inconspicuous job because if done perfectly, no one will ever notice.

In comic books, continuity has also come to mean a set of contiguous events, sometimes said to be "set in the same universe."
