The Loyalist Volunteer Force (LVF) was an Ulster loyalist paramilitary group in Northern Ireland. It was formed by Billy Wright in 1996 when he and his unit split from the Ulster Volunteer Force (UVF) after breaking its ceasefire. Most of its members came from the UVF's Mid-Ulster Brigade, which Wright had commanded. In a two-year period from August 1996, the LVF waged a paramilitary campaign in opposition to Irish republicanism and the Northern Ireland peace process. During this time it killed at least 14 people in gun and bomb attacks, almost all of them Catholic civilians killed at random. The LVF called off its campaign in August 1998 and decommissioned some of its weapons, but in the early 2000s a loyalist feud led to several killings. Since then, the LVF has been largely inactive, but its members are believed to have been involved in rioting and organized crime. In 2015, the security forces stated that the LVF "exists only as a criminal group" in Mid-Ulster and Antrim.

Ulster loyalism is a strand of Ulster unionism associated with working class Ulster Protestants in Northern Ireland. Like other unionists, loyalists support the continued existence of Northern Ireland within the United Kingdom, and oppose a united Ireland independent of the UK. Unlike other strands of unionism, loyalism has been described as an ethnic nationalism of Ulster Protestants and "a variation of British nationalism". Loyalists are often said to have a conditional loyalty to the British state so long as it defends their interests. They see themselves as loyal primarily to the Protestant British monarchy rather than to British governments and institutions, while Garret FitzGerald argued they are loyal to 'Ulster' over 'the Union'. A small minority of loyalists have called for an independent Ulster Protestant state, believing they cannot rely on British governments to support them. The term 'loyalism' is usually associated with paramilitarism.
