Conor McGregor shares four kids with his fiancée Dee Devlin

Conor McGregor is best known for his success in mixed martial arts but he’s also the proud father of four children.

The boxer has enjoyed a successful athletic career, but away from the ring he spends a lot of time with his fiancée, Dee Devlin, and their children. The pair welcomed their first son Conor Jr. in 2017 and daughter Croía joined the family in 2019. Devlin and McGregor expanded their family with the birth of their sons Rían in 2021 and Mack in 2023.

After Conor Jr. was born and McGregor became a father for the first time, he said during an appearance on RTÉ’s The Late Late Show, “I’m very proud and very blessed every day because the birth of my son has made me softer where I need to soften up. I’m overcome with joy and love. I never thought I would be that way.”

McGregor often spends time with his children, even when he’s training. While in Dubai in December 2023, he shared a video of himself taking his three older children for a run and added the caption, “Sunday in the sunshine with my kids, thank you God.”

Here’s everything to know about Conor McGregor’s children.

Conor Jack McGregor Jr., 7

McGregor and Devlin welcomed their first son, Conor Jr., on May 6, 2017. His father announced the news on Instagram with a photo of the new mom and their baby, and added the caption, “Dee and Junior are doing great everyone! Thank you for all the kind words, I am one proud and blessed Daddy.”

McGregor has encouraged Conor Jr.’s interest in MMA and boxing and took him to media events in the build-up to his fight with Floyd Mayweather in 2017 when he was just weeks old.

A few months after the fight McGregor said, “When he grows up, I’m going to put him into sport. I believe sport is the best thing you can do. I’ve already begun training him. He’s already leaps and bounds ahead of schedule.”

That same year, McGregor told MMA Fighting, “I want to show him my career, the crazy things I’ve done in my life, the crazy journey I’ve been on and then mostly show him what hard work can achieve. I can show him that if you work hard you can achieve great things.”

Paul Sutcliffe, who owns the boxing club where McGregor started his career, has also spoken about Conor Jr. following in his dad’s footsteps.

“Conor Jr is a natural,” he told The U.S. Sun in 2023. “He’s an athlete, no matter what he does. He’s got flexibility, he’s strong, he has no fear.”

Croía Mairéad McGregor, 5

McGregor and Devlin added Croía Mairéad to the family on Jan. 3, 2019. After her birth, the new dad-of-two wrote on Instagram, “Heading home with my two healthy babies and an energized and healthy SuperMam.”

Devlin confirmed her pregnancy with Croía on Instagram when celebrating her husband’s 30th birthday. She wrote, “Thank you for being you! Love you to bits from me, Conor Jr. and the bump.”

Croía has attended some of her dad’s fights and the boxer has shared on his Instagram about some of their special father-daughter moments. In April 2023, McGregor posted a series of photos of himself and Croía out to dinner with the caption, “Taking my real life Princess Croía to dinner ❤️.”

In January 2024, McGregor and Devlin threw a mermaid-themed party for Croía’s 5th birthday. The boxer posted a series of photos from the event and wrote in the caption, “Happy birthday my Croía, daddy loves you so much 🥰🧜‍♀️.”
