Ray Houghton's header in '88. The penalty shoot-out win in Italia 90. The victory at Giants Stadium in 1994. Robbie Keane's equaliser against Germany 14 years ago... they are all iconic moments in Irish sporting history.
"No competition is the same without the Irish there, we have seen it over the years."
The above quote wasn't just a throw-away comment from veteran striker Keane at last week's pre-tournament camp in Cork. The LA Galaxy forward spoke with passion, the record goalscorer, battling back from injury, determined to end his international career in style.
Of course, there was one instantly forgettable major championships.
The Republic fans converged on Poland in huge numbers four years ago but Giovanni Trapattoni's Irish side bowed out in ignominious fashion after comprehensive defeats by Croatia, Spain and Italy.
The current crop - 10 of whom were involved at Euro 2012 - are determined to make up for that disappointment this time around.
When the much-travelled Trapattoni failed to guide Irish to the 2014 World Cup in Brazil, it was time for a change.
Enter a seemingly unlikely partnership of Martin O'Neill, an experienced and successful club manager, and the volatile Roy Keane, arguably the greatest Republic player of all time.
Keane Saipan saga still triggers heated debate
Keane's infamous World Cup walk-out in 2002 still triggers heated debate up and down the Emerald Isle and beyond.
In a difficult Euro 2016 qualifying campaign, one moment stood out. Shane Long's outstanding strike against world champions Germany in October left the Republic's Euro 2016 destiny in their own hands.
It took a subsequent play-off win over Bosnia-Herzegovina to confirm their spot in France, but the Irish were back at a major tournament.
It will be O'Neill's first finals as a manager, but the European Cup winner with Nottingham Forest did captain Northern Ireland at the 1982 World Cup in Spain.
He feels there are similarities between his current squad and Billy Bingham's group of players.
"This particular squad have shown a desire to pull themselves around. You can make a lot of the late goals [we scored in the campaign]. If you do it often enough well you then think that there must be something about it," says O'Neill.
"A desire, a sort of never-say-die spirit. You think about way back and I can draw on 1982 with that Northern Ireland squad.
"The one thing we had then was a great, great desire and spirit. Really strong with a wee bit of talent in proper positions and some really strong characters. I think that's what we now have here. But the real test is yet to come."
The tests don't come more difficult than what many consider to be Euro 2016's group of death as the Republic open up against Sweden on Monday followed by contests with highly-fancied Belgium and invariably competitive Italy.
A tough task, but O'Neill's Ireland haven't come just make up the numbers.
It is a major tournament, and it just wouldn't be the same without the Republic.
