Mo-nah-se-tah or Mo-nah-see-tah (c. 1850 - 1922), aka Me-o-tzi, was the daughter of the Cheyenne chief Little Rock. Her father was killed on November 28, 1868, in the Battle of Washita River when the camp of Chief Black Kettle, of which Little Rock was a member, was attacked by the 7th U.S. Cavalry under the command of Lt. Colonel George Armstrong Custer. Mo-nah-se-tah was among the 53 Cheyenne women and children taken captive by the 7th Cavalry after the battle.
