Titleholder (Japanese: タイトルホルダー, foaled 10 February 2018) is a Japanese Thoroughbred racehorse. He showed very promising form as a two-year-old in 2020 when he won his first start before finishing second in the Tokyo Sports Hai Nisai Stakes and fourth in the Hopeful Stakes. In the following spring he won the Yayoi Sho and ran second in the Satsuki Sho before returning in the autumn to record his biggest win in the Kikuka Sho. He improved again as a four-year-old when he added victories in the Nikkei Sho, Tenno Sho (Spring) and Takarazuka Kinen.
