Ireland, Scotland, Thailand and The Netherlands will play a quadrangular T20 tournament to help them prepare for the Women's T20 Global Qualifiers at the end of August.
The Netherland will host the competition, with the sides playing six matches in seven days at Deventer from August 8-14.
All four teams are playing in the Global Qualifiers at the end of August, from which the top two teams will progress to the T20 World Cup in Australia in February 2020.
“2019 is a big year for women’s cricket in Ireland and we want to provide our squad with the best opportunity to qualify for the T20 Women’s World Cup," said Ireland Head Coach Aaron Hamilton.
"As such, this new tournament is timely and competitiveness of the four teams involved will definitely help with our preparations. With a home series just completed against the West Indies, and a Zimbabwe series to come, the Irish squad will definitely benefit from the volume of international fixtures throughout the summer.”
Steven Knox, Head Coach of Scotland Women’s cricket team, said: “It's great to have the opportunity to play six T20I’s against teams close to us in the world rankings.
"I'm delighted that the Cricket Scotland board have committed to the Scotland Women's team participating in this Quadrangular tournament in the Netherlands where conditions will be similar to those we'll experience a few weeks later in Scotland.
"As coach I believe it's the next step in the team's evolution from a predominantly UK-based pseudo English county team to a fully-fledged international team.”
Sean Trouw, Head Coach of KNCB Women said: “The series is a great opportunity for the team to play more competitive cricket and for us to be playing at home is a great chance to show what women’s cricket is all about.
"This series will be a great opportunity to grow the game locally and hopefully inspire a few more girls to take up the game. This is a great initiative for the women’s game and is a real boost to our cricket calendar for this year."
