Vivlos is a Japanese Thoroughbred racehorse and broodmare. She showed some promise as a juvenile in 2015 when she won a minor race on the second of her two starts. In the following year she was moved up in class and made steady progress, ending her season with a win in the Grade 1 Shuka Sho. As a four-year-old she defeated an international field to take the Dubai Turf and won the JRA Award for Best Older Filly or Mare. In 2018 she failed to win a race but finished second in both the Dubai Turf and the Hong Kong Mile. On her final racecourse appearance she finished second in the 2019 Dubai Turf.
