Sources differ on the precise year of Crazy Horse's birth, but most agree he was born between 1840 and 1845.
According to Šúŋka Bloká (He Dog), he and Crazy Horse "were both born in the same year at the same season of the year," which census records and other interviews place in 1842.
Ptehé Wóptuȟ’a (Encouraging Bear), an Oglala medicine man and spiritual adviser to Crazy Horse, reported that Crazy Horse was born "in the year in which the band to which he belonged, the Oglala, stole One Hundred Horses, and in the fall of the year," a reference to the annual Lakota calendar or winter count.
Among the Oglala winter counts, the stealing of 100 horses is noted by Cloud Shield, and possibly by American Horse and Red Horse owner, as equivalent to the year 1840–41.
Oral history accounts from relatives on the Cheyenne River Reservation place his birth in the spring of 1840.
On the evening of his son's death, the elder Crazy Horse told Lieutenant H.R. Lemly that the year of birth was 1840.

Crazy Horse was born to parents from two bands of the Lakota division of the Sioux, his father being an Oglala and his mother a Miniconjou.
His father, born in 1810, was also named Tȟašúŋke Witkó (Crazy Horse).
Crazy Horse was named Čháŋ Óhaŋ (Among the Trees) at birth, meaning he was one with nature.
His mother, Tȟašína Ȟlaȟlá Wiŋ (Rattling Blanket Woman, born 1814), gave him the nickname Pȟehíŋ Yuȟáȟa (Curly) or Žiží (Light Hair) as his light curly hair resembled her own.
She died when Crazy Horse was only four years old.

One account said that after the son had reached maturity and shown his strength, his father gave him his name and took a new one, Waglúla (Worm).
Another version of how the younger Crazy Horse acquired his name is that he took it after going through the haŋbléčheya ceremony.
Crazy Horse's cousin (son of Hewáŋžiča, Lone Horn) was Maȟpíya Ičáȟtagya (Touch the Clouds).
He saved Crazy Horse's life at least once and was with him when he died.
