She plays a time-traveling English nurse-turned-surgeon on Starz's action-packed historical drama "Outlander," which has its roots in Scotland. But in real life, leading lady Caitriona Balfe is Irish. Born in Dublin and raised in the village of Tydavnet near the Northern Ireland border, she left behind her old life as Ireland's most successful international model for a new one as an actress, and it's paying off: In addition to "Outlander," Cait starred in the Jodie Foster-directed 2016 drama "Money Monster" with George Clooney and Julia Roberts, 2019's "Ford v. Ferrari" alongside Christian Bale and Matt Damon and, more recently, the critically acclaimed "Belfast."

Dublin-born Andrew Scott has been acting since the '90s but enjoyed a huge career boost when he played the hot priest on season 2 of "Fleabag" in 2019. That Golden Globe-nominated performance came after he delighted audiences as Moriarty on the BBC series "Sherlock," which earned him a BAFTA Award for best supporting actor.

Surprisingly, Saoirse Ronan was born on American soil — in the Bronx, to be exact. But when she was 3, her Irish parents returned to their native country and raised their only child in County Carlow. Saoirse ("It's pronounced either 'Sir-sha' — like 'inertia' — [or] a lot of Irish people would say 'Seer-sha,'" she told Yahoo! Movies) got her big international break in 2007's "Atonement," a performance that earned her Oscar, Golden Globe and BAFTA Award noms, and she's continued to make cool, interesting film choices ever since. She picked up another Golden Globe and Oscar nomination for her work in 2017's "Lady Bird" and more recently picked up best actress nominations for her work in Greta Gerwig's 2019 adaptation of "Little Women."

"Harry Potter" franchise and "The Comey Rule" star Brendan Gleeson has been in showbiz for four decades — and his career continues to reach new heights. The Dublin-born actor — who won an Emmy and in 2022 scored a best supporting actor Oscar nomination for his work in "The Banshees of Inisherin" — is also the father of actors Domhnall Gleeson and Brian Gleeson.

_

Although Domhnall Gleeson's acting resume was initially dominated by cool indie-flavored fare and theater work, he's perhaps most recognizable now from his more mainstream roles as Ron Weasley's eldest brother, Bill, in the "Harry Potter" movies, Rachel McAdams' love interest in the rom-com "About Time" or the lead in the kids' flick "Peter Rabbit." The Dublin-born son of actor Brendan Gleeson also, of course, starred as the ruthless General Hux in the "Star Wars" franchise.

Like a fine wine, Pierce Brosnan just gets better looking with age. The former James Bond hails from Navan, Ireland, and these days calls Hawaii home.

If you love period pieces as much as we do, you already know Allen Leech. From his earlier work on "Rome" and "The Tudors" to his more recent roles in "Downton Abbey" and "The Imitation Game," he's clearly a great fit for historical drama. As for the most Irish thing about him? "I love the Irish culture in relation to music and song," Allen — who hails from the Dublin suburb of Killiney — told USA Today. "For that reason, I play the guitar. And I love traditional Irish music."

Michael Fassbender might have been born in his father's homeland, Germany, but he was raised in his mother's — Ireland — from the age of 2. He grew up in Killarney in County Kerry where he served as an altar boy and his parents ran a restaurant. One of his earliest professional acting roles was the ultimate score for an Irishman: Michael starred in a Guinness commercial in 2004. He married actress Alicia Vikander in 2017; they welcomed a baby in 2021.

"Poldark" star Aidan Turner might have played hunky Cornwall, England, antihero Ross Poldark on the popular BBC/PBS period drama, but he's actually Irish. The Clondalkin, Ireland-born actor also drew raves for playing Kíli in the successful "The Hobbit" film franchise.

Daniel Day-Lewis was born and raised in England but in 1993, he became a citizen of Ireland, where he's lived full time since the late '90s. That — and the fact that he won his first of three best actor Oscars for playing an Irishman in "My Left Foot" (and nailed a Northern Irish accent when he starred in "In the Name of the Father") — make him pretty darn Irish in our book.

Chris O'Dowd cannot be put in a box. He always kills it on screen, whether he's doing comedies like "Bridesmaids," period dramas like the BBC downer "The Crimson Petal and the White" or hip, hot fare (remember when he popped up as Jessa's finance-guy husband on HBO's "Girls" and when he starred on the British sitcom "The IT Crowd"?). But the Boyle, Ireland-raised actor's personal productions might be his best yet: He and wife Dawn O'Porter welcomed their first son, Art, in 2015, and second son, Valentine, in 2017.

We know what you're thinking — "Olivia Wilde is Irish?!" But yes, it's true: The "Don't Worry Darling" actress-director is actually an Irish citizen. Olivia was born in New York City and raised in Washington, D.C., but spent her summers in Ardmore, Ireland. She also studied acting on the Emerald Isle after high school and eventually acquired an Irish passport.

Fiona Shaw is an Irish actress who has built quite the resume. The County Cork-born actress is perhaps best known for starring as Petunia Dursley in the "Harry Potter" films and as Marnie Stonebrook on HBO's "True Blood," though she's also achieved major success in the theater world. In 2018, she starred in "Lizzie" alongside Chloe Sevigny and Kristen Stewart and also appeared on "Killing Eve."

"Once Upon a Time" fans loved Colin O'Donoghue as Captain Killian "Hook" Jones on the ABC fantasy series.

_

Like countryman Colin O'Donoghue, Sarah Bolger also appeared on "Once Upon a Time" (she played Princess Aurora). But the Rathfarnham, Ireland-raised butcher's daughter — who starred as a college student opposite Olivia Wilde in the 2015 horror flick "The Lazarus Effect" — might be more familiar for her work as a child actress: Sarah and her real-life sister Emma wowed audiences as the immigrant siblings in Jim Sheridan's emotionally charged 2002 film festival darling "In America."

Dublin-raised Jason O'Mara is one of those actors you see on screen and go, "Oh yeah, him!" After getting his start in British theater, he got his big international break on HBO's acclaimed "Band of Brothers" miniseries and has appeared in dozens of TV shows and films ever since. But he's probably more recognizable these days for his work on "Agents of S.H.I.E.L.D.," "The Good Wife," "Vegas" and as the voice of Batman and Bruce Wayne in the DC Universe's animated movies. In 2017, he split from actress wife Paige Turco, with whom he has a son.

Katie McGrath never intended to be an actress. After graduating from Dublin's Trinity College with a degree in history, Katie — who grew up in Ashford, Ireland — started working as a fashion journalist before joining the wardrobe department on "The Tudors." There, the stunning green-eyed brunette was encouraged to get in front of the camera. Roles in TV's "Merlin," "Dracula" and the Hallmark holiday movie "A Princess for Christmas" quickly followed. She has since appeared in the big-budget films "Jurassic World" and "King Arthur: Legend of the Sword."
