Young-Man-Afraid-of-His-Horses [Tȟašúŋke Kȟokípȟapi] (1836 – July 13, 1893), also translated as His-Horses-Are-Afraid and They-Fear-Even-His-Horses, was a chief of the Oglala Sioux. Commonly misinterpreted, his name means They fear his horse or His horse is feared, meaning that the bearer of the name was so feared in battle that even the sight of his horse would inspire fear. He is known for his participation in Red Cloud's War, as a negotiator for the Sioux Nation after the Wounded Knee Massacre, and for serving on delegations to Washington, D.C.
