Henley Women's Regatta, often abbreviated to "HWR" or "Women's Henley", is a rowing regatta held at Henley-on-Thames, England. Chris Aistrop and Rosemary Mayglothling were jointly responsible for setting up the Regatta in June 1988 and Aistrop was the first chairman. It was first held in 1988, as a response to the absence of women's events at Henley Royal Regatta at that time. While Henley Royal Regatta now offers eight women's events, Women's Henley has continued to build and expand. Henley Women's Regatta now lasts three full days, and includes time trials for over-subscribed events.
