Ian Madigan (born 21 March 1989) is an Irish former professional rugby union player for Leinster, Bordeaux, Bristol Bears, Ulster and Ireland.

[5] With the departure of Johnny Sexton to Racing Métro at the start of the 2013–14 season, Madigan was vying with New Zealander Jimmy Gopperth, who joined the province from Newcastle Falcons, for the role of first choice fly-half.

Throughout that season the selectors adopted a system of alternation between the two players, with neither individual being considered to have nailed down the number ten jersey.

With seconds remaining in the first half of extra time, Madigan attempted a huge pass which was read and intercepted by Springbok Bryan Habana, who sprinted 50 metres to score a try which effectively put the game beyond Leinster's reach.

[6] This loss, coupled with Leinster's failure to get to the play-off stage of the Pro 12 league, ended a woeful season for the Dublin-based province and the effective sacking of head coach Matt O'Connor.

[8] In December 2015, it was announced that Madigan would be leaving Leinster at the end of the season to join French Top 14 club Bordeaux Bègles.

[19] Madigan was included in Ireland's squad for the summer tour of North America in June 2013, where he started both Tests against the US Eagles in Houston and Canada in Toronto.

In the November end of year internationals, he made a further three substitute appearances against Samoa, Australia, and New Zealand; a dramatic encounter in which Ireland were denied an historic first-ever win over the All Blacks in the final minute of the Test match.

[22] He was included in the national squad for the 2014 Autumn internationals series, making a start at fly-half for the Test against Georgia, and two substitute appearances against South Africa and Australia.

[26] His imminent departure to play club rugby in France was cited as a reason for his omission, with the selectors opting instead to select players who remain in Ireland.

Ireland lost the series 2–1, but claimed a historic first win over South Africa on home soil in the first Test in Cape Town.
