Joseph Baena

Joseph Baena (born October 2, 1997) is an American actor and fitness model. Joseph Baena is the son of Arnold Schwarzenegger and Mildred Patricia "Patty" Baena.

Early life Joseph Baena is the son of Arnold Schwarzenegger and Mildred Patricia "Patty" Baena. At birth, he became the legal son of his mother's husband at the time, Rogelio Baena. Rogelio and Patty separated shortly after.

When Baena was 13, he—and the world—learned that Arnold Schwarzenegger was his biological father, after the media published this news four months after Schwarzenegger's final day as governor of California. Baena decided to keep his last name instead of taking the last name Schwarzenegger.

Baena is of Austrian and Guatemalan ancestry. He has one half-sibling from his mother (Jackie Rozo), and four half-siblings from his father: Katherine, Christina, Patrick, and Christopher Schwarzenegger. His paternal half-brother Christopher was born 5 days before Baena, on September 27, 1997.

Career Fitness modeling Baena was featured on the cover of the Men's Health March 2022 issue, highlighting his fitness practices and his familial bonding with his father.

In March 2021, Baena started training Brazilian jiu-jitsu at Checkmat Northridge.

Realty career Baena expressed an interest in starting a career in real estate on Instagram in May 2021. After taking the necessary classes and passing the state boards, Baena successfully earned his State of California Realtor's License in 2022 and is currently affiliated with Aria Properties in Los Angeles, California. By competing, "the young Arnold son says that he is not just breaking down the 'dance floor' but is also 'breaking the barriers in his family.'" His body type, flexibility and fitness training were not particularly well adapted to dancing, which he foresaw as a challenge.

Baena offered the opinion that physical fitness became his watchword because, "I couldn't keep up with the other guys." In a podcast interview, he confessed that he was both unfit and bullied. In college, he had an epiphany: "I was like the chubby kid in my... crew, and, um yeah. It wasn't until I joined swim my sophomore year..." When he could not run, leaving him unfit for soccer and basketball, he settled on joining the swim team.

Amateur bodybuilding On 28 March 2026, Baena competed in the 2026 NPC Natural Colorado State Championships in Men's Classic Physique and Open Bodybuilding. He notably placed 1st in the "True Novice" and "Novice" Classic Physique divisions. He also placed 1st in the "Men's Bodybuilding - Open Heavyweight" division. He came 2nd in Open Class C, making him the runner-up to the overall.
