Does Conor McGregor Have Kids? About His Children

Conor McGregor is one of the most recognizable faces in sports, but the Irish athlete is not just a UFC fighter—he’s also a proud father of four.

Together with his longtime fiancée, Dee Devlin, who has been by his side throughout much of his career, McGregor shares Conor Jr., Croía, Rían, and Mack, whom they welcomed in late 2023. When revealing that he and Devlin were expecting their fourth child, McGregor expressed his excitement in a June 2023 interview on Live With Kelly and Mark.

“So we’ve got the new one, the next one on the way. A couple more weeks, we’ll be able to find out what the sex is of the baby, and we’re very excited back home,” he said. “A lot of great things happening. I’m very blessed. I’m very thankful. Everyday, I smile up to God and thank God.”

McGregor has frequently expressed his desire to introduce his eldest son to MMA and boxing. He even took Conor Jr. to media events leading up to his 2017 fight with Floyd Mayweather when the baby was just a few weeks old. After the fight, McGregor shared his plans for his son’s future, saying, “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.”

Paul Sutcliffe, the owner of the boxing club where McGregor began his career, has also weighed in on Conor Jr.’s potential. In 2023, he told The U.S. Sun, “He’s an athlete, no matter what he does. He’s got flexibility, he’s strong, he has no fear.”

Over a year after the birth of their second child, McGregor announced that he proposed to Devlin, who he has been in a relationship with since 2008, on August 8, 2020—just before she turned 33.

Croía has attended some of her dad’s fights, and the two share a close bond, with McGregor often calling his only daughter a “real-life Princess.”

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

Earlier, on Christmas Eve 2020, McGregor announced they were expecting their second son with an Instagram post featuring Conor Jr. holding up an ultrasound image. The caption read, “Happy Christmas everyone, from my family to yours. So much to look forward to in 2021.”

In February 2024, McGregor shared a heartfelt photo of himself holding Rían, accompanied by the caption, “Hand on heart, my son Rían McGregor, I love you so much ❤️🙏.”
