The territorial extent covered by the term Ulster may vary, reflecting the prevalent deep political and cultural divisions.
- The province of Ulster, one of the historic four provinces on the island of Ireland – comprising nine counties, six in Northern Ireland and three in the Republic of Ireland.
- Northern Ireland is sometimes referred to as Ulster, particularly by the unionist community, in this sense comprising the six UK-ruled counties only.
Political and paramilitary organisations, parties and movements having "Ulster" as part of their name are almost invariably on the Unionist side; military and police units having such names are often accused of a pro-Unionist bias. That is, however, not necessarily the case with names in other spheres including "Ulster". For example, Ulster sports associations and teams often form part of an all-Ireland structure and thus, while not overtly political, are favourably regarded by Irish Nationalists.
Flags
- The divergent meanings of "Ulster" are reflected in divergent flags:
- The Flag of Ulster which represents the whole of the historic province of Ulster
