Commuter (Irish: Comaitéir) is a brand of suburban rail services operated by Iarnród Éireann in the Republic of Ireland, serving the cities of Dublin, Cork, Limerick and Galway.

It was also used in some signage and advertising, giving the diesel commuter networks a consistent look for the first time.

These additional trains are currently used on the outer Dublin suburban network to destinations including Portlaoise, Carlow and Athlone.

A further order for an additional 51 cars, formed into 17 three-car units and totalling €140 million, was made in March 2009, for use to other suburban destinations, including Dundalk, Portlaoise, Longford and M3 Parkway.

Instead, an Irish Rail logo referencing the then booking website was displayed on the side of the trains.

Since March 2013 the new bilingual logo has been introduced across the company's rolling stock, including the Commuter service.

This is designed to eliminate customer confusion between the two names Iarnród Éireann and Irish Rail and create a more unified image.
