The 22-year-old was just eight years old when her father died in 2006.
Steve Irwin, affectionately known as The Crocodile Hunter, has died at the age of 44, after his chest was pierced by a stingray beard on Australia’s Great Barrier Reef.
Irwin revealed his new daughter’s name on Friday, which was also her wedding anniversary with husband Chandler Powell, calling her Grace Warrior Irwin Powell.
Sharing a photo on social media, Irwin wrote, “March 25, 2021. Celebrate the two loves of my life. Happy first wedding anniversary to my darling husband and birthday to our beautiful daughter.
“Grace Warrior Irwin Powell. Our gracious warrior is the most beautiful light.
“Grace is named after my great-grandmother and Chandler’s family members dating back to the 1700s.
“His first names, Warrior Irwin, are a tribute to my father and his legacy as the most incredible wildlife warrior.
“Her last name is Powell and she already has such a kind soul, just like her father.
“There are no words to describe the endless amount of love in our hearts for our sweet little girl. She chose the perfect day to be born and we feel extremely blessed. ”

Irwin married Powell, a former professional wakeboarder, at her family’s famous Australian Zoo in Queensland on March 25 last year – hours before major wedding ceremonies were banned under lockdown restrictions.
