The party had five TDs elected in the [[2002 Irish general election]], an increase of four from the previous election. At the [[2007 Irish general election|general election in 2007]] the party had expectations of substantial gains,<ref>{{cite web |url=http://www.sinnfein.ie/contents/9022 |title=Sinn Féin up and running for General Election |publisher=Sinn Fein |date=29 April 2007  |access-date=20 April 2010 |archive-url=https://web.archive.org/web/20100504183645/http://www.sinnfein.ie/contents/9022 |archive-date=4 May 2010 |url-status=dead}}</ref><ref>{{cite news |url=http://www.anphoblacht.com/news/detail/18472 |title=Dáil General Election Profile : Councillor Gerry Murray, Mayo |date=29 March 2007 |newspaper=[[An Phoblacht]] |access-date=20 April 2010 |archive-url=https://web.archive.org/web/20120229170005/http://www.anphoblacht.com/news/detail/18472 |archive-date=29 February 2012 |url-status=dead}}</ref> with poll predictions that they would gain five<ref>{{cite news |url=https://www.telegraph.co.uk/news/uknews/1552197/Sinn-Fein-looks-to-coalition-with-Republic.html |title=Sinn Fein looks to coalition with Republic |first=Tom |last=Peterkin |date=21 May 2007 |access-date=20 April 2010 |newspaper=[[Daily Telegraph]] |location=London |archive-url=https://web.archive.org/web/20111212024853/http://www.telegraph.co.uk/news/uknews/1552197/Sinn-Fein-looks-to-coalition-with-Republic.html |archive-date=12 December 2011 |url-status=live}}</ref> to ten seats.<ref>{{cite news |first=Henry |last=McDonald |url=https://www.theguardian.com/world/2007/may/27/ireland2 |title=Sinn Fein's hopes dashed in Irish elections |date=27 May 2007 |newspaper=[[The Observer]] |location=London |access-date=20 April 2010 |archive-url=https://web.archive.org/web/20130831080210/http://www.theguardian.com/world/2007/may/27/ireland2 |archive-date=31 August 2013 |url-status=live}}</ref> However, the party lost one of its seats to [[Fine Gael]].

On 26 November 2010, [[Pearse Doherty]] won a seat in the [[2010 Donegal South-West by-election|Donegal South-West by-election]]. It was the party's first by-election victory in the [[Republic of Ireland]] since 1925.<ref>{{cite web |url=http://www.belfasttelegraph.co.uk/news/local-national/republic-of-ireland/sinn-fein-wins-by-landslide-in-donegal-southwest-byelection-15015148.html |archive-url=https://archive.today/20120719235813/http://www.belfasttelegraph.co.uk/news/local-national/republic-of-ireland/sinn-fein-wins-by-landslide-in-donegal-southwest-byelection-15015148.html |url-status=dead |archive-date=19 July 2012 |title=Sinn Fein wins by landslide in Donegal South-West by-election |date=27 November 2010|newspaper=[[Belfast Telegraph]] |issn=0307-5664 |location=Belfast |language=en |access-date=1 January 2011}}</ref> After negotiations with the left-wing Independent TDs [[Finian McGrath]] and [[Maureen O'Sullivan (politician)|Maureen O'Sullivan]], a [[Technical Group]] was formed in the Dáil to give its members more speaking time.<ref>{{cite news |url=http://www.irishtimes.com/newspaper/breaking/2010/1210/breaking53.html |title=SF forms Dail Technical Group |first=Stephen |last=Collins |date=10 December 2010 |newspaper=[[The Irish Times]] |issn=0791-5144 |location=Dublin |language=en-ie |access-date=13 January 2011 |archive-url=https://web.archive.org/web/20110313134618/http://www.irishtimes.com/newspaper/breaking/2010/1210/breaking53.html |archive-date=13 March 2011 |url-status=live}}</ref><ref>{{cite news |url=http://www.rte.ie/news/2010/1126/donegal.html |title=Pearse Doherty elected in Donegal South–West |work=[[RTÉ News]] |location=Dublin |date=26 November 2010 |access-date=13 January 2011 |archive-url=https://web.archive.org/web/20110101092530/http://www.rte.ie/news/2010/1126/donegal.html |archive-date=1 January 2011 |url-status=live}}</ref>

In the [[2011 Irish general election]] the party made significant gains. All its sitting TDs were returned, with Seán Crowe regaining the seat he had lost in 2007 in Dublin South-West. In addition to winning long-targeted seats such as [[Dublin Central (Dáil constituency)|Dublin Central]] and [[Dublin North-West (Dáil constituency)|Dublin North-West]], the party gained unexpected seats in [[Cork East (Dáil constituency)|Cork East]] and [[Sligo–North Leitrim (Dáil constituency)|Sligo–North Leitrim]].<ref name=IT1>{{cite news |url=http://www.irishtimes.com/newspaper/breaking/2011/0227/breaking2.html |title=Fine Gael poised to lead next government as FF collapses |first=Kilian |last=Doyle |date=27 February 2011 |newspaper=[[The Irish Times]] |issn=0791-5144 |location=Dublin |language=en-ie |archive-url=https://web.archive.org/web/20111101114307/http://www.irishtimes.com/newspaper/breaking/2011/0227/breaking2.html |archive-date=1 November 2011 |url-status=live}}</ref> It ultimately won 14 seats, the best performance at the time for the party's current incarnation.

The party achieved their greatest contemporary result in the [[2020 Irish general election]], topping the first-preference votes with 24.5% and winning 37 seats. Due to poor results in the 2019 local elections and elections to the European Parliament, the party ran only 42 candidates and did not compete in [[Cork North-West (Dáil constituency)|Cork North-West]]. The party achieved unexpected success in the early counting, with 27 candidates being elected on the first count.<ref>{{cite news |url=https://www.rte.ie/news/election-2020/results/ |title=General Election Results |work=[[RTÉ News]] |access-date=15 February 2020 |archive-date=13 February 2020 |archive-url=https://web.archive.org/web/20200213130309/https://www.rte.ie/news/election-2020/results/ |url-status=live}}</ref><ref>{{cite news |url=https://www.bbc.com/news/world-europe-51441410 |title=Fianna Fáil largest party but Sinn Féin celebrate |date=11 February 2020 |work=[[BBC News]] |access-date=15 February 2020 |language=en-GB |archive-date=14 February 2020 |archive-url=https://web.archive.org/web/20200214200429/https://www.bbc.com/news/world-europe-51441410 |url-status=live}}</ref> Party leader Mary Lou McDonald called the result a "revolution" and announced she would pursue the formation of a government including Sinn Féin.<ref>{{cite news |url=https://www.reuters.com/article/us-ireland-election-idUSKBN2030CJ |title=Irish nationalists Sinn Fein demand place in government after strong election showing |date=9 February 2020 |work=[[Reuters]] |access-date=15 February 2020 |language=en |archive-date=15 February 2020 |archive-url=https://web.archive.org/web/20200215020843/https://www.reuters.com/article/us-ireland-election-idUSKBN2030CJ |url-status=live}}</ref> Ultimately negotiations to form a new government led to Fianna Fáil, Fine Gael and the [[Green Party (Ireland)|Green Party]] agreeing to enter a majority [[32nd government of Ireland|coalition government]] in June.
