Ortensia was an Australian thoroughbred racehorse. A sprinter, she won Group One races on three continents. The mare died while in foal to Redoutes Choice on the weekend of 4/5 June 2016, having to be euthanized due to a tumour that developed on one of her lungs, severely reducing her ability to breathe. She has two fillies a yearling by Choisir and a weanling by Dream Ahead. Ortensia was 10 years old.
