Information on how to sign up for the Tag, Touch and Sevens events is available on irishrugby.ie/thegathering.
Minister for Transport, Tourism & Sport, Leo Varadkar TD, said: "I'm really looking forward to this event which promises a feast of rugby. The Irish are a sports-mad nation, and sporting occasions like this are a crucial part of the Gathering. I want to commend the IRFU for organising this rugby festival."
At the launch of the initiative, Ireland captain Jamie Heaslip said: "There are times as a professional player when you wish you weren't in the middle of your pre-season and the GUINNESS Mid-Strength Irish Rugby Gathering Festival is one of those.
"The festival will deliver a great mix of rugby which will allow people to pit their skills against international teams and even get some pre-season training in.
"The social side of summer rugby events is amazing and this is one of those events that promises to be the highlight of the summer, so I encourage everybody to pull a team together and get involved."
Rory Sheridan from GUINNESS said: "We are delighted to support the IRFU and Leinster Rugby's Gathering initiative. The tournament provides a great mix of rugby and with such a large concentration of teams and competitions all in the one venue, through the support of UCD, the GUINNESS Mid-Strength Irish Rugby Gathering certainly promises to deliver a real festival of rugby and a carnival atmosphere on August 17."
