Pierce O'Leary v Mark Chamberlain

Dublin’s own Pierce O’Leary puts his IBO world super-lightweight title on the line at the 3Arena on Saturday 1 August 2026, facing English contender Mark Chamberlain in what is a genuine world-title fight night. O’Leary, 26, is unbeaten in 19 professional bouts and a nine-time Irish amateur champion - a Dubliner making his 3Arena headline debut in front of a home crowd that has followed his rise. Chamberlain brings a 17-1-1 record and 12 knockouts to the contest, and previously had to withdraw from a March date with O’Leary through illness. This time the bout is on. If you follow Irish boxing, this is not a night to miss.

What to expect

Twelve rounds of super-lightweight boxing at world level, with O’Leary’s IBO belt at stake. Both fighters carry knockout power - O’Leary has 11 stoppages from 19 wins, Chamberlain 12 from his 18 fights - so the crowd can expect a contest with real finish potential. O’Leary is currently ranked fifth by the WBC and 12th by the IBF; a performance here would push him toward the very top of the division. The card also features an undercard of Irish fighters, so the evening runs across several hours and there is competitive boxing from the opening bout. Doors open at 6:30pm, with the main event ringwalk expected around 9:00pm.

Getting there

The 3Arena sits right on the North Wall Quay beside the East Link Bridge in Dublin 1, which puts it within easy reach of the city centre. The Luas Red Line runs to the Point Village stop directly outside the venue - the most straightforward option from most parts of the city. Dublin Bus routes also serve the area. If driving from outside Dublin, the M1, M7, and M50 all connect to the city; the Port Tunnel links the northern motorways to the docks area and the 3Arena. Parking is available nearby at the Point Village car park, but spaces fill early on a Saturday night so public transport is the more reliable choice. Taxis and rideshares drop off on North Wall Quay.

While you’re in Dublin

The Docklands area around the 3Arena has changed considerably over the past decade, with bars and restaurants along the quays worth exploring before or after the event. A short walk into the city centre opens up everything from Temple Bar to the IFSC quarter. There is more to see in Dublin and across Co. Dublin.
