Coreoleuciscus splendidus, also known as the swiri or Korean splendid dace, is a species of fish from the cyprinid family endemic to rivers of the Korean peninsula. It was first scientifically described by Tamezo Mori in 1935, who noted in 1936 that it could be found spawning in Gyeongsangbuk-do's Uljin County; a 1939 study also found it in the Geum and Seomjin rivers.
