The Japanese multimedia franchise Umamusume: Pretty Derby, created by Cygames, centers around the titular Umamusume (ウマ娘; horse girls), kemonomimi who replace horses in the series' fictional universe and compete in organized races as both racers and idols. The vast majority of Umamusume featured in the franchise are named after Japanese racehorses, with their names, designs, and characterization inspired by their real-life equivalents' careers and personalities. As of May 2026, there are 130 playable Umamusume in the Umamusume Pretty Derby mobile game, many of whom also appear in the anime and manga series, alongside numerous additional Umamusume and human characters who appear throughout the franchise.
The franchise depicts Umamusume as all-female cursorial humans with the physical traits and characteristics of horses, including horse tails, horse ears, increased strength, high metabolisms, and the ability to run as fast as 70 km/h (43 mph). Each Umamusume wears a ribbon or other accessory on one ear (or wears a hat that tilts toward one ear) that indicates their real-life namesake's gender; to the viewer's right (proper left ear) indicates it was a mare, while to the viewer's left (proper right ear) indicates it was a stallion.
