Koraun Mayweather is an American recording artist and entrepreneur best known as the eldest son of boxing legend Floyd Mayweather Jr.
He has taken a very different path from his father and focused on music, building his own identity as a rapper and producer under the stage name King Koraun.
Over the years, he has released independent music and stayed away from the celebrity lifestyle that often surrounds the Mayweather family.
Public attention has also followed him because of his close relationship with his late mother, Josie Harris, whose death in 2020 became one of the most widely reported moments involving the Mayweather family.
Despite carrying one of the most recognizable surnames in sports, Koraun has consistently expressed interest in creating his own career outside the boxing ring.

Koraun Mayweather Biography
He was born in the United States and is the eldest child of Floyd Mayweather Jr. and Josie Harris. Koraun Mayweather’s childhood unfolded while his father was establishing himself as one of boxing’s biggest attractions.
During those years, Floyd captured multiple world championships across different weight classes and eventually became one of the highest-earning athletes in sports history.
Growing up in that environment meant elite athletes, celebrities, and championship events frequently surrounded Koraun. Even so, much of his upbringing remained centered around family rather than boxing.
His mother, Josie Harris, played a significant role throughout his childhood. She frequently appeared with her children during family events and remained closely involved in raising them.
Koraun also developed strong relationships with his younger siblings, including Zion Mayweather and Jirah Mayweather.
Although Floyd’s career required extensive travel around the world, Koraun has spoken publicly about maintaining a relationship with his father throughout his life.
As the oldest member of the Mayweather children, he has often attracted attention whenever Floyd shares family moments on social media or during public appearances.
Floyd Mayweather’s Son
Being Floyd Mayweather’s eldest son has naturally brought Koraun significant public attention.
His father retired with a perfect professional record of 50 victories without a defeat, won world championships in five different weight divisions, and became one of boxing’s highest-earning athletes.
Those accomplishments created expectations that one of his sons might eventually enter professional boxing.
Koraun chose a different direction. He built his interests around music and creative production.
That decision reflects a broader trend among several members of the Mayweather family, who have pursued careers outside professional sports despite growing up around boxing.
Koraun has occasionally appeared alongside Floyd during family celebrations, birthday events, and public appearances, but he has never shown serious interest in launching a competitive boxing career.
His father has repeatedly supported his children’s individual ambitions instead of pushing them toward boxing simply because of the family name.
For Koraun, that support allowed him to pursue music while avoiding comparisons with one of the greatest fighters of his generation.
Mother: Josie Harris
Koraun shared a particularly close relationship with his mother, Josie Harris. Harris was an actress, entrepreneur, and television personality who remained a constant presence throughout her children’s lives.
She and Floyd Mayweather were together for many years and had three children together before eventually ending their relationship.
On March 10, 2020, Harris died at her home in Valencia, California, at the age of 40. The Los Angeles County Medical Examiner later ruled her death an accidental drug overdose involving fentanyl and alprazolam.
Authorities did not suspect foul play. Her death had a profound impact on Koraun and his siblings.
Siblings
Koraun Mayweather is the oldest biological son of Floyd Mayweather Jr. He has three biological half-siblings and one adopted half-brother through his father’s family.
His biological siblings are:
Zion Shamaree Mayweather, born in 2001. Zion is Koraun’s younger brother. Like Koraun, he is the son of Floyd Mayweather Jr. and the late Josie Harris. Zion has largely stayed away from professional sports and has pursued business interests, including launching his own clothing brand.
Jirah Mayweather, born in 2003. She is Koraun’s younger sister and is also the daughter of Floyd Mayweather Jr. and Josie Harris. Jirah has maintained a relatively private life while occasionally appearing alongside her father at public events.
Iyanna Mayweather, widely known as Yaya Mayweather born in 2000. She is Koraun’s half-sister through Floyd Mayweather Jr.’s relationship with Melissa Brim. Iyanna has received significant media attention over the years because of her public profile and her music ventures.
Koraun also grew up with Devion Cromwell, whom Floyd Mayweather Jr. helped raise during his relationship with Melissa Brim.
Devion is not Floyd’s biological son but has long been regarded as part of the Mayweather family.
Career
Koraun Mayweather has focused his professional ambitions on music. Performing under the name King Koraun, he has released independent hip hop tracks across streaming platforms while continuing to develop his own sound.
He has worked to establish himself within the music industry through original releases and collaborations.
His songs typically combine modern hip hop production with themes surrounding ambition, success, family, and personal experiences.
Several of his releases have attracted attention among fans already familiar with the Mayweather family, although he continues to build his audience independently. Music has remained his primary creative outlet throughout adulthood.
Outside of recording, Koraun has occasionally promoted his work through social media, where he shares updates about upcoming projects and studio sessions.
He has also shown interest in entrepreneurship, reflecting a business mindset similar to several members of the Mayweather family.
While boxing made the Mayweather surname famous around the world, Koraun’s career demonstrates that he intends to create his own legacy through entertainment rather than professional sport.
That decision has become one of the defining aspects of his public identity. It continues to separate him from expectations that he would eventually step into the ring like his father.
