Early life and family
Koraun was born on November 17, 1999, in the United States. He is the oldest of Mayweather’s four children: Koraun, Iyanna (Yaya), Zion, and Jirah. Floyd shares Koraun, Zion, and Jirah with Josie Harris (who passed away in 2020), and Iyanna with Melissa Brim. Growing up, Koraun lived part of his life away from the ring, even though the public often saw him beside his famous father at events.
Reports and features note that Koraun attended West Ranch High School in Santa Clarita, California. This detail shows that, despite the spotlight, his family also focused on normal school life and community.
Choosing music over boxing
Unlike many children of athletes, Koraun did not try to follow his father into boxing. Instead, he built a creative path in music, releasing tracks under the name King Koraun (also seen as KingRjun on streaming platforms). Media profiles and his own social posts show that he has put out singles and projects over the years and continues to treat music as his main passion.
Coverage from mainstream outlets and magazines has highlighted his artist identity, describing him as focused on writing, recording, and planning his releases. This creative direction lets him express himself away from boxing expectations and shape his own brand.
Public moments with his father
Even though their careers are different, you can find several warm public moments between Floyd and Koraun. During the first year of the COVID-19 pandemic, Floyd shared videos of himself teaching Koraun how to box—a small family scene that fans enjoyed online. It showed the bond between father and son, and the way Floyd still passes on basic ring skills, even if Koraun’s main dream is music.
Photos from events also show Koraun attending major family milestones with his father and siblings. These appearances remind fans that, behind the headlines, the Mayweathers are a family with normal laughs, trips, and birthday parties.
Coping with loss and moving forward
A big and painful chapter in Koraun’s life was the death of his mother, Josie Harris, in March 2020. The Los Angeles County Medical Examiner later ruled her death an accidental overdose (mixed drug toxicity of fentanyl and alprazolam). News coverage at the time described how the family grieved and how Floyd later posted tributes. This event deeply affected all three of Harris’s children, including Koraun, and shaped the years that followed.
Since then, stories have shown the Mayweather family trying to heal and support each other—traveling, staying in touch, and celebrating small wins. These steps matter for a young adult building a career while dealing with private pain in public view.
Online presence and everyday interests
On Instagram (@kingkoraun), Koraun gives small peeks into daily life—studio moments, friends, and simple hobbies. His posts signal a relaxed tone and sometimes mention gaming or casual interests. This lighter side helps fans see him as a regular 20-something, not only as the son of a superstar.
On streaming platforms, searches for KingRjun surface a growing list of singles and projects. While he is still developing his sound and audience, the catalog shows steady output and a desire to be judged on the music, not only on his last name.
Relationship with the Mayweather name
Carrying the Mayweather name brings attention, but it also brings pressure. Media often compare children to their famous parents. In Koraun’s case, he has chosen to build his own lane, which is a smart, healthy move. By focusing on writing and recording, he can control the story: he is not just “Floyd’s son”, he is an artist with his own goals.
At the same time, his connection to the family is strong. Mainstream coverage of Floyd’s children often mentions respect, gratitude, and support as values inside the household. That positive frame helps Koraun keep balance between family legacy and personal growth.
Final thoughts
Koraun Mayweather shows that you can respect a strong family legacy and still choose your own road. He keeps his life simple, stays close to loved ones, and spends time on his craft. For fans of the Mayweather family—or for anyone who likes to see young artists grow—his journey is worth watching.
