Umamusume: Pretty Derby

Umamusume: Pretty Derby is a Japanese multimedia franchise created by Cygames. The franchise centers on anthropomorphized racehorses known as Umamusume (ウマ娘; lit. 'horse girls'), who compete in races inspired by real-life race tracks managed by the Japan Racing Association. Most of the characters are named and themed after actual racehorses, reflecting their namesakes' personalities, racing records, and relationships with other racehorses. Initially announced in 2016 as a mobile game, the franchise soon expanded to include multiple anime series, manga, and live concerts.

The game was scheduled to debut in late 2018 for iOS and Android devices, but it was delayed to a February 2021 release, with a Windows client releasing a month later on DMM Games. The game was later released on Google Play Games in April 2023. The game was released in Korean by Kakao Games and Traditional Chinese by Komoe Game in June 2022, with the former language getting a PC version in a stand-alone client a year later, then later in Simplified Chinese by Bilibili in August 2024. An English-language edition was released worldwide in June 2025 for the aforementioned platforms, alongside a Steam release for both the Japanese and English versions.

The franchise has been received positively, both domestically in Japan and worldwide following the game's global release in 2025. The franchise has also had a significant cultural impact, with observers notably remarking its positive impact to the sport of horse racing and bringing awareness to the stories of racehorses.
