Seina Imamura (Japanese: 今村 聖奈, Hepburn: Imamura Seina; born November 28, 2003) is a Japanese-born Thoroughbred horse racing jockey.
Imamura entered the JRA (Japan Racing Association) Horse Racing School in 2018 and made her debut as a jockey in March 2022. Her father, Yasunari, is an assistant trainer of Yuji Iida's stable and former jockey who won the Grade 1 Nakayama Daishogai in 2001.
On July 3, 2022, Imamura won a graded stakes race on her first attempt, winning aboard T M Spada in the Group 3 CBC Sho. She became the fourth jockey in history to achieve this feat, as well as the second Japanese female jockey (after Nanako Fujita in 2019) to win a graded stakes race at a JRA racecourse.
In 2026, Imamura won the Yushun Himba (Japanese Oaks) aboard Juryoku Pierrot, becoming the first Japanese female jockey in history to win a Group 1 JRA race. She is also the second jockey in history (after Shigefumi Kumazawa) to win a Japanese classic race in their first start.
