Biddy gave her a belt in the gob and left her sprawling on the floor
Then the war did soon engage, t'was woman to woman and man to man
Shillelagh law was all the rage and a row and a ruction soon began"
- The Trope Namers are the University of Notre Dame's varsity sports teams and their belligerent Leprechaun mascot, who in turn got the name from Father William Corby, who was twice as President of the University of Notre Dame and served with the "The Fighting Sixty-Ninth" 69th New York Infantry Regiment, an Irish regiment during the American Civil War.
- Irish girl Clover in the comic Blue Monday is easily the most violent person in the entire comic.
- Matt Murdock, a.k.a. Daredevil is the biggest example of this trope in comics. The son of an Irish-American boxer, Jack "The Devil" Murdock, Matt Murdock prowls the rooftops of Manhattan's Hell's Kitchen neighborhood as Daredevil.

- Hellblazer: His native Liverpool being at least as Irish as Boston in places, John Constantine probably counts, although he isn't really much of a scrapper, preferring to let cockney Chas or Violent Glaswegian Header handle that sort of thing.

- Inverted in Back to the Future Part III: Seamus McFly keeps counseling Marty about staying out of fights and keeping his cool, although this is probably because his own brother Martin was very much the embodiment of this trope. This didn't end well.
Seamus: Martin used to let men provoke him into fighting. He was concerned people would think him a coward if he refused. Thats how he got a bowie knife shoved through his belly in a saloon in Virginia City.
- In Braveheart, Wallace's most eagerly violent soldier is an Irishman who joined the campaign not for the sake of freedom, but for the chance to kill Englishmen. He's also insane, or deeply religious with a sick sense of humor.

- Burn Notice: Ex-IRA fighter Fiona Glenanne is quick to recommend that any problem be solved by charging in with guns and bombs blazing, especially when it involves children being endangered. Her suggestions usually get shot down in favor of something less conspicuous, but when the firepower's needed Fi is always ready to provide.
Michael: Do you have some explosives?Fiona: I'm going to pretend you didn't ask that.
- Monty Python's Flying Circus "Bookshop Sketch": 101 Ways to Start a Fight by "an Irish gentleman whose name eludes me."

Now Clancy was a peaceful man

After Clancy left the scene,
He never looked for trouble
That's a fact you can assume,
But never-the-less when trouble would press
Clancy lowered the boom!
- Ireland's National Anthem "Amhrán na bhFiann"/"A Soldier's Song". Now, to be fair, a lot of national anthems are partially or entirely about how incredibly good the country in question is at war. Ireland's is still in the "entirely" category, being about how much Irish people fight and that's it.
In valley green, on towering crag
Our fathers fought before us
And conquered 'neath the same old flag
That's proudly floating o'er us
We're children of a fighting race
That never yet has known disgrace
And as we march, the foe to face
We'll chant a soldier's song
