The IRFU Interprovincial Championship was a rugby union competition between the four provinces of Ireland – Ulster, Leinster, Munster and Connacht – and, for a brief period the Irish Exiles, run by the Irish Rugby Football Union.

History

Original competition

The Interprovincial Championship, often shortened to the Interpros, was run as a distinct competition from 1946–47 to 2000–01,IRFU Team History Archive, Interprovincial Championship Results, page 1, page 2, page 3 with the 2001–02 fixtures being fulfilled by the match-ups in the newly formed Celtic League.Gerry Thornley, "Interpro series to be cut back", The Irish Times, 18 December 2001 For a time in the 1980s, the IRFU ruled that Irish diaspora players should play for Connacht, in an attempt to strengthen the weakest of the four provinces.Conor Neville, "The 10 Best Connacht Players Ever To Play For Ireland", Balls.ie, 16 February 2016 The Irish Exiles took part for four years (1992–93 – 1995–96). Fixture pressure meant the competition ceased after the 2001 edition.

URC Irish Shield

In 2021, the United Rugby Championship introduced regional shields with the Irish provinces competing for the URC Irish Shield. Initially the pool included results against other non-Irish sides but from 2023 onwards, the URC announced that the regional pool shields of the competition would be decided only by results between the teams within each pool. With this change, the URC effectively reintroduced a form of the Interprovincial Championship for the first time since 2002 (albeit with professional, not representative, teams).

Points difference as tiebreaker was never used in the tournament.

There was not a full set of matches to complete the competition in 2001–02. The rules for deciding placing used for the Celtic League/Magners League/Pro12 for that season were used to decide the placings in the interpro table.

1995 The 1995 IRFU Interprovincial Championship was the first to be held since rugby union was declared open to professionalism. At this stage the Irish provinces were still representative teams, not professional clubs.Peter O'Reilly, "Ulster coach warns on power balance", The Sunday Tribune, 22 September 1996 Many involved in the game were concerned that domestic clubs could not afford to pay players, who could be lost to professional teams in England.Jim Stokes, "IRFU tackle 'pro' issue", Belfast Telegraph, 28 August 1995 In September, the IRFU confirmed that, for this season, only senior international players would be paid,Jim Stokes, "International players only to 'cash in'", Belfast Telegraph, 12 September 1995 with a one-year moratorium on payment for club and provincial players.Jimmy Davidson, "Market forces takes strangle hold on rugby", Belfast Telegraph, 4 November 1995 As the situation developed, match fees became available for Heineken Cup and Interprovincial matches.Tyrone Howe, "Local game needs a professional outlook", Belfast Telegraph, 13 January 1996 Leinster won the Interprovincial title for the first time in twelve years.Jim Stokes, "Whiteout!", Belfast Telegraph, 23 December 1995

At this stage the Irish provinces were still representative teams, not professional clubs. However, the provinces were now offering contracts and match fees for Heineken Cup and Interprovincial matches, although these contracts sometimes conflicted with players contracted to clubs in England."Reid's cautionary note on contracts", Belfast Telegraph, 23 March 1996

1997 The IRFU offered new contracts for provincial players for this season. Full-time players would receive a retainer of £25,000, plus a win bonus of £500 for Heineken Cup matches. Part-time players would be paid a retainer of £7,500, plus a match fee of £400 for Interprovincial matches and £800 for the Heineken Cup, and a win bonus of £450 for both competitions."Seventy six players win IRFU contracts", Irish Independent, 17 July 1997 Each province could have a maximum of 30 contracted players.Barry Coughlan, "IRFU brings home the message with provincial contracts", Irish Examiner, 1 May 1998

1998

This season, the tournament adopted a new format, with each team playing each other home and away. The tournament points system was adopted from Super 12 and the Tri Nations, with four points for a win and two for a draw, a bonus point for scoring four or more tries in a match, and a bonus point for losing by seven points or less.Grant Robbins, "Restructured Interpros puts emphasis on attack", Evening Herald, 14 August 1998 This led to an average of over four tries scored per match.Andy Ward, "Top notch Inter-pro series puts IRFU back on track", Irish Independent, 27 October 1998
