2019 Ireland Tri-Nation Series

The 2019 Ireland Tri-Nation Series was a cricket tournament that was held from 5 to 17 May in Ireland. It was a tri-nation series featuring Bangladesh, Ireland and the West Indies, with all the matches played as One Day Internationals (ODIs). The ODI fixtures were part of Bangladesh and West Indies' preparation for the 2019 Cricket World Cup. Bangladesh also played a 50-over warm-up match against Ireland A on 5 May 2019.

The West Indies were the first team to qualify for the final, after they beat hosts Ireland in the fourth match of the series. Bangladesh also qualified for the final, after they beat the West Indies in the fifth match. Bangladesh won the series, after beating the West Indies by five wickets in a rain-affected final. It was the first time that Bangladesh had won a multi-team international tournament.

Squads
In late April 2019, Taskin Ahmed and Farhad Reza were added to Bangladesh's squad. Mark Adair was added to Ireland's squad, replacing Stuart Thompson, who was ruled out due to injury. After initially naming a squad for their first two ODIs, Ireland named an unchanged squad for the remaining fixtures.
