Aisling Daly is a retired Irish female professional mixed martial artist who last competed in the UFC women's strawweight division. Daly had been a professional MMA competitor since 2007.

Daly is well known for her participation in the reality TV series "The Ultimate Fighter: A Champion Will Be Crowned", season 20. The 12 episodes featured a single elimination tournament that was used to determine two finalists to compete for the first ever UFC woman's straw weight belt. Daly was eliminated in the quarterfinals, and as a result of her showing was offered and accepted a fight on the undercard of the championship fight, which she won.

On 30 January 2017 she officially retired from MMA due to an abnormality in a routine brain scan making it unlikely for her to be cleared to fight again.
