Diana Prazak is an Australian professional boxer who held the WBC female super-featherweight title from 2013 to 2014. She is the first Australian boxer to have been ranked as the best active boxer, pound-for-pound, by BoxRec.

Amateur career

At the age of 27, Prazak joined a local boxing gym to lose weight. She took her first amateur fight at 64 kg after six months of training. As an amateur fighter Prazak had six fights and won them all via stoppage. The last such fight was for a national title, making her the Australian Amateur Light Welterweight Champion. This was her last amateur fight before turning professional.

Professional career

Prazak made her professional boxing debut on 13 March 2010 in Moonee Valley, Victoria, Australia. She was defeated via unanimous decision after six rounds with fellow Australian Sarah Howett. In 2012, she moved to Los Angeles and began training under Lucia Rijker.
In 2013, she fought against Super Featherweight Champion Frida Wallberg, who was defeated by her in Sweden with a knock out in the 8th round. Prazak won the title, Wallberg was hospitalized and received emergency surgery to relieve the pressure on her brain from a cerebral haemorrhage.
This fight, and the road leading to it, is captured in the documentary Bittersweet, showing Dutch former professional boxer Lucia Rijker training Diane to prepare her for the fight.
When Prazak retired from boxing, she had won 14 professional fights and lost 4. In 2025, Prazak was inducted into the International Women's Boxing Hall of Fame.
