Little Raven, also known as Hosa (Young Crow), (born c. 1810 — died 1889) was from about 1855 until his death in 1889 a principal chief of the Southern Arapaho Indians.

While in Denver, Little Raven learned some of the white man's ways, such as how to smoke cigars and eat meat with utensils.

[3] The Arapaho chiefs were so welcoming that the newcomers named the first county in the territory after the tribe, as well as streets in both Denver and Boulder.

[citation needed] Along with six chiefs of the Southern Cheyenne and three others of the Arapaho, Little Raven signed the Fort Wise Treaty on 18 February 1861, but he became frustrated when whites failed to comply with the agreement.

The treaty allotted the Southern Arapaho a reservation between the Arkansas and Cimarron rivers in Indian Territory (present-day Oklahoma).

[2] Following the Battle of the Washita on 27 November 1868, Little Raven led the Southern Arapaho to Fort Sill for protection.

[2] Eventually Little Raven settled at Cantonment in present-day Blaine County, Oklahoma, where the old military hospital served as his home.
