The Battle of Honsinger Bluff is a conflict between the United States Army and the Sioux people on August 4, 1873 along the Yellowstone River near present-day Miles City, Montana.

This is U.S. territory acquired from the Crows in 1868.

The main combatants are units of the U.S. 7th Cavalry under Lt. Col. George Armstrong Custer, and Native Americans from the village of the Hunkpapa medicine man, Sitting Bull, many of whom will clash with Custer again approximately three years later at the Battle of the Little Big Horn in the Crow Indian Reservation.
