List of Ulster-related topics

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
 The Ulster Banner, used from 1953 to 1972 as the banner of the former Government of Northern Ireland. Today it is still used by some Northern Ireland sports teams.
