Hollow Horn Bear (Lakota name Matȟó Héȟloǧeča) (ca. 18501913) was a Brulé Lakota leader during the Indian Wars on the Great Plains of the United States. Hollow Horn Bear was born in what today is Sheridan County, Nebraska. He was the son of chief Iron Shell. Although he initially raided the Pawnee, he later was involved in harassing forts along the Bozeman Trail with other Sioux leaders between 1866 and 1868. During this period, he became famous as the chief who defeated Capt. William Fetterman. However, he began to favor peace with the whites during the 1870s. He became a celebrity in the East, and was present at several functions as a native representative. He was featured on a 14-cent postage stamp and on a five dollar bill.
