The 29000 Class is a type of four-car Diesel Multiple Unit operated by Iarnród Éireann (Irish Rail).

The railcars were the first to be shipped with the new Commuter branding rather than the "Arrow" branding previously used, and as such were the first Iarnród Éireann rolling stock (other than DART EMUs and Enterprise stock) not to feature the company's traditional orange and black livery, which was phased out from passenger service in 2006.

They were largely returned to their intended Commuter services since deliveries of 22000 Class DMUs commenced in 2007, which displaced them from Sligo line workings in 2008, though there are still a few services to and from Rosslare Europort with the 29000 Class DMUs.

The November 2009 timetable change finally saw the end of the 29000s running West of Dublin from Heuston to Newbridge/Kildare and Carlow.

In addition, these trains occasionally operate services from Dublin Connolly to Belfast Grand Central and Sligo MacDiarmada.
