Lonhro, nicknamed The Black Flash, was an Australian champion racehorse. He was from the first crop of the champion Octagonal out of the Group One-placed Shadea, who also produced the Group One winner Niello. Lonhro raced from two to five years of age and won 26 races, including 25 stakes races, ranging in distance from 1,100 to 2,000 metres. These included 11 Group One wins and 18 wins at weight-for-age. He was bred and owned by Woodlands Stud and trained by John Hawkes. Lonhro's name is based on the stock exchange code of the London Rhodesian Mining and Land Company, LONRHO. This arose from his foaling description as "tiny but perfect", a label ascribed to Roland "Tiny" Rowland, CEO of the company. The horse's name is deliberately misspelt. Lonhro died on 19 April 2024, at the age of 25.
