12 teams will compete in the tournament, split into three groups, with France, England, Brazil, Portugal, Chile, Japan, Guatemala and Qatar set to make up the tournament line-up.
Stephen Kenny's Under-21 side are set to travel to Provence, France for the prestigious tournament which begins on Monday, June 3 with Ireland set to face China in their first group game.
Ireland will then face Mexico on Thursday, June 6 before their final group game against Bahrain on Sunday, June 9.
The semi-finals are set for Wednesday, June 12 with the final set for Sunday, June 15 as Ireland compete in their first Toulon Tournament since 2002.
"Ireland have never qualified for a major tournament at Under-21 level so Toulon represents one of the highest tournament experiences at this age level, which will stand them well in the future," said U-21 manager Stephen Kenny.
"The first game is against China. Guus Hiddink is over the Under-21s so it shows the huge amount of resources they're putting into their teams. Of course, Hiddink previously managed South Korea, Australia and Holland at the World Cup.
"Mexico will be very strong, quarter-finalists in the last Under-20s World Cup, and have a great history of success at this level having previously competed in the Olympics. With Qatar 2022, Bahrain will be pushing to qualify for that tournament, it will be at the forefront of their minds, and the players who will play in Toulon will be pushing to be part of that tournament in a few years time.
"China, Mexico and Bahrain will all have players from 1996 & 1997 whilst we'll have players like Adam Idah, who is a 2001, and even Troy Parrott, who is a 2002, so it will be a great exposure for our players. Three different styles of play which will be very intriguing and the weather will be very hot in Toulon so it presents a challenge. We're coming off the back of a good performance against Luxembourg in March and we're looking forward to the competition."
