Ishino Sunday (イシノサンデー, May 29, 1993 – August 18, 2024) was a former Japanese thoroughbred racehorse and stud. He was known as the first horse to win two three-year-old exclusive races in both turf and dirt when he snatched the Satsuki Sho and Derby Grand Prix in 1996. Together alongside Bubble Gum Fellow, Dance in the Dark and Royal Touch, they were known as the four heavenly kings of 1996 Sunday Silence's progenies.
