Ireland are to host the West Indies and Bangladesh in a one-day international tri-series in May.
The games at Malahide and Clontarf will bring the number of men’s international fixtures being staged in Ireland next year to 16.
The Irish will also face England, Afghanistan and Zimbabwe in ODI games.
The highlight of their 2019 calendar is the four-day Test match against England at Lord’s on 24-27 July, which will be Ireland’s second at the top level.
Ireland played their first ever Test match in May 2018, losing by five wickets to Pakistan at Malahide.
The ODI tri-series starts on 3 May, with the final on 17 May.
The West Indies were last in Ireland in September 2017 but their scheduled one-day match at Stormont was abandoned without any play.
Cricket Ireland plans to develop a new stadium at Abbotstown in west Dublin and chief executive Warren Deutrom said they have spread the venues for their 2019 fixtures in an effort to preserve the quality of their pitches: “In all, we will be hosting eight matches in Dublin and eight matches across Northern Ireland.
“The venues have been chosen to spread the fixture load across our four international-rated grounds – with five matches at Malahide, three at Clontarf, five at Stormont and three at Bready.
“The configuration of fixtures also allows teams involved in the Tri-Series to all be located in the same city to reduce travel impacts and maximise training and acclimatisation opportunity for those sides as part of their build-up to Cricket World Cup 2019.
“This rotation of matches will also maximise our ability to play on new pitches in most matches. The fact though that we do not have enough international standard pitches to provide a new one for every match will give a sense of why the Board was keen to see a fifth international cricket ground constructed at Abbotstown.”
