Katie Taylor, the 39-year-old Irish boxer, will have her final professional fight at Dublin’s Croke Park stadium on September 5, 2026 [1, 2, 3, 4]. She will face Flora Pili of France, who is undefeated with a 12-0 record, in a bout for the undisputed junior welterweight titles including the vacant WBC belt [1, 3, 4]. Taylor currently holds the IBF, WBA, and WBO junior welterweight championships and has a professional record of 25 wins and 1 loss, with 6 knockouts [1, 4].

Croke Park, often called the "cathedral of Irish sport," holds about 80,000 to 82,000 spectators and will host what promoter Eddie Hearn expects to be the largest crowd ever for a female athlete's individual event [1, 2, 3, 4]. Hearn said there "won't be a dry eye in the house" during the event and called it "the biggest crowd in the history of female sport for an individual athlete" [2].

Taylor is widely regarded as one of the best and most influential female boxers, credited with popularizing women's boxing across the UK and Europe [2, 4]. She first made history at 15 by fighting in Ireland’s first sanctioned female amateur bout in 2001 [2]. She won Olympic gold in London 2012, when women’s boxing debuted at the Games [1, 2, 4].

Her only professional loss came in 2023 to Chantelle Cameron, though she avenged that defeat later that year [1, 3, 4]. Most recently, Taylor defeated Amanda Serrano in July 2025 in New York during their trilogy fight [1, 3, 2]. She described the upcoming fight as "the perfect way to end it (my career), by becoming undisputed champion again in our national stadium which has such a special place in Irish hearts" [1]. She added, "We've actually brought boxing back to Croke Park. This has been on my career bucket list, especially the last few months, but this is beyond my wildest dreams" [3].

Flora Pili holds the full WBC junior welterweight title but it is currently vacant as champion Sandy Ryan is on maternity leave acting as champion in recess [4]. The September 5 bout will contest all major junior welterweight belts for full undisputed status [1, 4].
