A convincing 3-0 win over BATE Borisov sparked wild celebrations in Tallaght stadium.
Trailing 1-0 from the reverse leg in Belarus, Stephen Kenny's men played their opponents (who participated in the Champions League group stages last season) and booked their place in Europe.
Guaranteed a spot in the Europa League, they will now wait and see who they play in the Champions League playoff when the draw is made on Friday.
Back to tonight and after the final whistle the Dundalk players forgot the fact that they have to travel to Galway on Friday and went wild in the pissing rain, here are the best images captured by the SportsFile photographers in attendance.
Fanastic stuff, the manner of the victory was the most impressive aspect, a comfortable dismantling of a side who played in the Champions League group stages last season.
The gaffer gave a great interview in the immediate aftermath:
"We want to go into the Champions League" - Stephen Kenny is already looking ahead! #LOIinEurope #DUNvBATE https://t.co/DPdSBxulkM

And Stephen Kenny was quick to heap praise on his players for their performance too:
