The unified heavyweight champion of the world, Oleksandr Usyk, is married to Yekaterina Usyk, also known as Kateryna. The couple, who tied the knot in 2009, share a deep bond that has been a source of strength for Usyk as he prepares for his upcoming rematch against Daniel Dubois on July 19, 2025, at Wembley Stadium.

Yekaterina, while maintaining a low profile, is a prominent figure in Ukraine. She runs the Usyk Foundation, a charitable organization aimed at providing humanitarian aid amid the ongoing conflict in Ukraine. The foundation focuses on several critical areas: supporting the Ukrainian Armed Forces, delivering aid to civilians, and raising international financial assistance for Ukraine.

In a statement made in April 2022, Yekaterina reflected on the emotional toll of the war, revealing that her husband lost 10 kilograms in just one week due to the shock and horror of the conflict. This personal insight highlights the challenges both she and Usyk have faced as they navigate their lives during tumultuous times.

The couple has four children: two sons, Kyrylo and Mykhalio, and two daughters, Yelizaveta and Maria. The family was forced to evacuate their home in Vorzel, Bucha, as Russian troops overran the area, which resulted in the loss of many personal belongings. Usyk expressed the difficulty of explaining the situation to his children, stating, “My children are asking, ‘Daddy, why do they want to kill us?’ I don’t know how to answer that.”

Despite the challenges, Usyk remains committed to his family and his sport. He has spoken candidly about the sacrifices he has made to reach the pinnacle of boxing. After his first victory over Tyson Fury, Usyk noted he missed significant family events, including birthdays and holidays, as he focused entirely on his training.

Looking ahead, Usyk’s rematch with Dubois is highly anticipated. The fight is set to take place a week later than initially scheduled, with ring walks expected around 21:50 BST (16:50 ET). Coverage of the main card will begin at 17:30 BST (12:30 ET). Dubois, the IBF king, has expressed his determination for revenge, claiming he should have won their first encounter.

Usyk, on the other hand, expressed gratitude for the chance to fight for the undisputed championship once more, thanking Dubois for “taking care” of his IBF belt. The matchup promises to be a thrilling contest, showcasing the resilience and dedication of both fighters, and reflecting the personal and professional challenges they have navigated.

As the world watches, Yekaterina will undoubtedly be in Usyk’s corner, supporting him as he steps into the ring once more.
