Seán Dermot Fintan O'Leary (born 24 May 1973) is an Irish-British broadcaster. He presented the television talent show The X Factor on ITV from 2007 until its final series in 2018, with the exception of 2015. Since 2021, O'Leary has presented ITV's This Morning on Fridays, school holidays and bank holidays alongside Alison Hammond, a role expanded to the remainder of the week on a rotation with the departures of Phillip Schofield and Holly Willoughby in the summer and autumn of 2023.
O'Leary began his radio career working as a disc jockey at Essex Radio. From 2001 to 2003, he was a presenter for London's indie rock station XFM. O'Leary joined BBC Radio 2 in 2004 and currently presents the Saturday morning breakfast show.
Seán Dermot Fintan O'Leary was born on 24 May 1973 in Colchester, Essex, the son of Irish parents Maria and Seán; he has had Irish citizenship since birth.[1] He attended primary school in nearby Marks Tey and later joined St Benedict's Catholic College in Colchester. His complacent attitude at school caused him to fail all but two of his GCSEs.[2] Following that, O'Leary re-took his school-leaving qualifications. This allowed him to later start his A-Level courses at Colchester Sixth Form College. He eventually studied for a degree in Media Studies with Politics at Middlesex University.[3]
Growing up, he was a member of The Boys' Brigade Christian youth organisation.[4] When he was in his late teens, he played American football for the Colchester Gladiators and the Ipswich Cardinals, where he wore the number 32.
O'Leary started as a disc jockey at BBC Essex,[5] based in Southend-on-Sea, before becoming a runner on the TV show Light Lunch with Mel Giedroyc and Sue Perkins and then a presenter at Channel 4 as part of the original presenting line-up of the channel's T4 strand, before moving on to present Big Brother's Little Brother (the companion show to Big Brother) on E4 from 2001 onwards. Also in 2001, O'Leary appeared on Lily Savage's Blankety Blank.[6] In 2004, Dermot hosted the TV show Shattered.
On 29 March 2007, it was announced that O'Leary would replace Kate Thornton as the new host of ITV's The X Factor for at least two series. On 27 March 2015, O'Leary confirmed that he had quit The X Factor after eight years to pursue other projects. Via his Twitter account, he said:
O'Leary was replaced by Olly Murs and Caroline Flack, who previously co-hosted The Xtra Factor, the behind-the-scenes companion programme, together in 2011 and 2012.[7]
On 29 March 2016, O'Leary returned to The X Factor as a presenter, replacing Murs and Flack, for the show's 13th series. In a statement, he said:
From 2010 to 2019, O'Leary presented the National Television Awards for ITV. Since 2010, O'Leary has hosted Soccer Aid on ITV, a celebrity football match in aid of the charity Unicef. In 2011, O'Leary hosted the Saturday night entertainment show The Marriage Ref on ITV. In September 2013, O'Leary hosted BRITs Icon: Elton John, a one-off music celebration for ITV.
In 2013, O'Leary presented the ITV campaign From the Heart, which encouraged viewers to consider organ donation. In January 2014, O'Leary filled in for Phillip Schofield for a week when he guest presented This Morning opposite Holly Willoughby.[8]
In 2017, O'Leary co-presented the 37th BRIT Awards with Emma Willis. In March 2017, O'Leary guest-presented nine episodes of The Nightly Show on ITV.

On 27 November 2007, it was announced that Big Brother: Celebrity Hijack was to be O'Leary's last series of Big Brother. After seven years, he made his final Big Brother appearance on 28 January 2008.
In March 2007, O'Leary signed a year-long contract with Channel 4 to appear on Hollyoaks. However, this was shortened after a series of disputes on set. Jim Rowe, a series writer at the time, said, "He couldn't follow even the simplest commands. It goes to show how vastly different presenting is to acting". O'Leary hasn't acted since. In 2009, O'Leary presented an episode of The Paul O'Grady Show, standing in for Paul O'Grady.
In March 2014, O'Leary made a return to Channel 4, where he presented the Live From Space season for three consecutive nights.[10]
O'Leary was a presenter for Comic Relief in 2005, 2011 and 2013. He also presented Sport Relief in 2012. In August 2006, O'Leary signed a deal to present the game show 1 vs. 100, which aired on Saturday nights on BBC One in combination with The National Lottery Draws.

O'Leary joined BBC Radio 2 in September 2004, presenting a Saturday afternoon show titled Dermot's Saturday Club, which ran from 2pm to 4pm. Following a number of changes to the length and timing of O'Leary's programme, due in part to the arrival of Chris Evans to Radio 2 and his role as presenter of The X Factor, his show was broadcast between 3pm and 6pm from April 2009 until its end on 21 January 2017. It focused on new music and had featured live sessions. O'Leary also hosted Radio 2's coverage of the BRIT Awards and South by Southwest. He won Sony Gold Awards for Music Programme of the Year in 2008, 2010, and 2013.[15]

O'Leary opened The Rodillian Academy in 2001. He is one of nine presidents of the Young People's Trust for the Environment[22] and is a patron of the international children's film festival CineMagic, a registered charity for young people based in Belfast.[23] He has campaigned on behalf of Make Poverty History, and visited Sierra Leone with CAFOD accompanied by his father. He is also a patron of the male cancer awareness campaign Everyman.

In a 2003 interview, O'Leary praised the Socialist Workers Party but quipped that they would "take all of [his] money", so he instead supported the Labour Party.[31] He supports Arsenal F.C., Celtic F.C. and London Irish RFC.[32] He can be heard on the Footballistically Arsenal podcast with his friends and fellow Arsenal fans Dan Baldwin and Boyd Hilton; on the show, it was mentioned that he owns shares in the club.

In 2007, O'Leary was an usher at the wedding of Holly Willoughby.[33] He is a practising Roman Catholic.[34] In an interview with Peter Stanford of the Daily Telegraph in February 2008, he "cheerfully" admitted using contraception while living with his future wife: "I do get it in the neck from some Catholics who say I am a buffet Catholic, picking and choosing the bits I like or don't like."[35]
O'Leary co-owned the Fishy Fishy restaurants in Brighton and Poole.[36] The Poole restaurant closed in 2013,[37] and the Brighton restaurant closed in 2016.[38]
