Home Nations (often written as the common noun home nations) is a term used to refer to the four constituent countries of the United Kingdom (UK) — England, Scotland, Wales and Northern Ireland — collectively but as separate entities, distinct from the UK as a state.

Both British and Irish media frequently use the term Home Nations to include Ireland as a whole, often when referring to sporting events. Although the Republic of Ireland is no longer part of the UK, it is generally considered to have an especially close relationship with Britain with the likes of Sky Sports giving plentiful coverage to Irish sport, for example the Irish national football team's games. The British Broadcasting Corporation (BBC) also give good coverage to the Republic on football-related programmes like Match of the Day and Football Focus. Popular Irish rugby union team's games are broadcast live on Sky Sports and the BBC in both Ireland and Britain.
