Conor McGregor stands as one of the most recognized figures in mixed martial arts, celebrated for his achievements in the UFC and his charismatic public image. Beyond his combat sports career, McGregor is also a father to four children: Conor Jr., Croía, Rían, and Mack, all of whom he has with his partner, Dee Devlin.
McGregor and Devlin have been a couple since 2008 and exchanged vows in 2025, following over a decade together. Throughout the years, the pair have occasionally offered glimpses into their family life, raising their children away from the constant glare of public attention.

McGregor has frequently voiced his aspiration to introduce his firstborn son to the disciplines of MMA and boxing. He even accompanied Conor Jr. to media engagements leading up to his 2017 bout against Floyd Mayweather when the baby was merely a few weeks old. Post-fight, McGregor outlined his vision for his son’s future, stating, “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 proprietor of the boxing club where McGregor commenced his career, has also commented on Conor Jr.’s potential. In 2023, he remarked to The U.S. Sun, “He’s an athlete, no matter what he does. He’s got flexibility, he’s strong, he has no fear.”
Croía Mairéad McGregor
McGregor and Devlin welcomed their second child, a daughter named Croía, on January 3, 2019. Following her birth, McGregor shared the announcement on Instagram, writing, “Heading home with my two healthy babies and an energized and healthy SuperMam.”
More than a year after the arrival of their second child, McGregor revealed that he had proposed to Devlin, his long-term partner since 2008, on August 8, 2020—shortly before her 33rd birthday.
Croía has been present at some of her father’s fights, and they share a close connection, with McGregor often referring to his only daughter as a “real-life Princess.”

When he revealed that he and Devlin were expecting their fourth child, McGregor expressed his enthusiasm in an interview on Live With Kelly and Mark in June 2023.
“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 stated. “A lot of great things happening. I’m very blessed. I’m very thankful. Everyday, I smile up to God and thank God.”
