"An incredible legacy": 6 key moments from Cillian O'Connor's legendary Mayo career
Legendary Mayo GAA forward Cillian O’Connor has announced his retirement from inter-county football.
The 34-year-old from Ballintubber has informed the Mayo senior football management team of his decision to retire and leaves behind a sterling legacy in the Green & Red.
Here are 6 moments that define the career of a seven-time Connacht Champion, a two-time National League winner, a two-time All-Star, a two-time Young Player of the Year and an All-Ireland Champion.
Start as you mean to continue; O’Connor made his first appearance for Mayo in the FBD League against GMIT in 2011, while still a teenager, scoring 1-5 before making a National League debut from the bench against Down. His Championship debut came from the bench again against London in Ruislip and he scored a point that day. He cemented a starting place by the time the Connacht Final against Roscommon rolled around and young O’Connor scored 0-8 of Mayo’s 0-13 that day as they were crowned Connacht champions; the first of 7 titles he would pick up for the Green & Red.
Although Mayo’s fantastic year was cut short at the All-Ireland semi-final stage, for the way he burst onto the scene, O’Connor was crowned the Young Footballer of the Year in 2011. He repeated this feat in 2012, capturing a second Connacht title and reaching the All-Ireland Final. It is a rare honour and one that he shares with his brother Diarmuid, who won the award in 2016 and 2017 and with Oisin Mullin, who won in 2020 and 2021. O’Connor was named captain in 2013 as Mayo would reach the All-Ireland Final for the second year in a row.
The 2016 and 2017 Mayo teams are undoubtedly two of the best to ever represent the county and were unfortunate to come up against a dynasty juggernaut in Jim Gavin’s Dublin. Cillian O’Connor was at the centre of these excellent Mayo teams and his late equaliser in both the 2016 final to force a replay and 2017 final to bring the game right down to the wire will live long in the memory.
Cillian O’Connor is a man for the history books and retires as the all-time leading goalscorer in Championship football. The record-breaking moment came quietly understated during a poor defeat against Kerry in the 2019 Super 8’s series down in Killarney, surpassing Colm ‘Gooch’ Cooper. That O’Connor achieved this at age 27 speaks volumes for his consistency and if injuries had not blighted him at various stages of his career, his record of 34-367 could have reached insurmountable levels. He also set the record for the highest individual scorer in any Championship match, putting 4-9 past Tipperary in the 2020 season.
In addition to a glittering inter-county career, Cillian O’Connor’s time around the Ballintubber senior team, beginning with his debut as a teenager in 2010, has seen the club celebrate its greatest days through the 2010s when they were the cream of the crop in the Mayo senior championship. From 2010 to 2019, they won the clubs only ever Moclair Cups (5 to be precise) with Cillian and his brothers at the forefront of the success; Cillian scored 0-3 in the 2010 final. They are a club hungry to return to the mountain top in Mayo and with his inter-county career over, they may have the 34-year-old to call upon for a few years yet as they attempt to reach the summit once more.
Few players have known the depths of Mayo heartbreak the way Cillian O’Connor has. When he stepped away from the panel in 2025, although he did not rule out a return, many in the county assumed that he would be just another in a long line of players from the great 2012-2017 teams to call it a day without a Celtic Cross in their back pocket. When Andy Moran became Mayo manager, Cillian got the call and returned to the fold. Although injuries restricted him to just 2 appearances in the Championship this year, Moran has hailed the role the veteran played in his All-Ireland winning squad.
“I am particularly grateful for the role Cillian played in 2026. His opportunities on the field were more limited than he had been accustomed to throughout his career, but his importance to the group never diminished. He led quietly, advised younger players and supported the management and his teammates throughout the year. He put the needs of the team ahead of his own,” said Moran. “I am delighted that after everything Cillian gave to Mayo football, he leaves the inter-county game as an All-Ireland champion.”
"Cillian leaves an incredible legacy in the green and red, and he can be immensely proud of the jersey he leaves behind for the next generation."
