RTÉ Sport will televise Dundalk's first round first leg tie with Riga FC on Wednesday 10 July from Oriel Park.
Peter Collins will present the coverage on RTÉ2 and RTÉ Player as Vinny Perth's side meet the Latvian champions.
Kick-off is 7:45pm from the County Louth venue which is expected to be sold out. John Kenny will be on commentary.
There are four rounds to progress through to get to the group phase of the competition. Partizani (Albania) or Qarabağ (Azerbaijan) await the winner in the second round.
Dundalk are guaranteed at least €800,000 in prize money, but that will rise to over €1.1m if they beat Riga.
The winner of the tie will be also guaranteed a third round Europa League qualifier, while the loser will go into the second round.
