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