Manuelito (1818–1893) was one of the principal war chiefs of the Navajo people before, during and after the Long Walk Period. His name means Little Manuel in Spanish. He was born to the Bitʼahnii Clan, near the Bear's Ears in southeastern Utah about 1818. As any Navajo, he was known by different names depending upon context. He was Ashkii Diyinii (Holy Boy), Dahaana Baadaané (Son-in-Law of Late Texan), Hastiin Chʼilhaajiní ("Black Weeds") and as Nabááh Jiłtʼaa (War Chief, "Warrior Grabbed Enemy") to other Diné, and non-Navajo nicknamed him "Bullet Hole".

Manuelito was a prominent Navajo leader who rallied his nation against the oppression of the United States military. For several years he led a group of warriors in resisting federal efforts to forcibly remove the Navajo people to Bosque Redondo, New Mexico via the Long Walk in 1864. After being relocated to Bosque Redondo, Manuelito was among the leaders who signed the 1868 treaty, ending a period of imprisonment in United States government internment camps and establishing a reservation for the Navajo.
