Irish cricket team in the West Indies in 2019–20

The Ireland cricket team toured the West Indies in January 2020 to play three One Day International (ODI) and three Twenty20 International (T20I) matches. The West Indies Cricket Board announced the tour dates in September 2019. In November 2019, Andrew Balbirnie was named as Ireland's captain across all three formats of international cricket.

Ahead of the first ODI match, the International Cricket Council (ICC) announced the use of technology to monitor front-foot no-balls for all matches during the tour. The third umpire called the front-foot no-balls, communicating this with the on-field umpires. It was used as a trial to see if it can be implemented further, without a detriment to the flow of the game. The trial was previously used in December 2019, in the matches between India and the West Indies.

The West Indies won the first two ODIs to take an unassailable lead in the series. The West Indies won the third ODI by five wickets, winning the series 3–0. It was the West Indies first ODI series win at home since beating Bangladesh in August 2014. For the first T20I, Jacqueline Williams was named as the third umpire, becoming the first woman to officiate as a third umpire in a men's international cricket match. The T20I series was drawn 1–1, after the second match finished in a no result due to rain.
