The Battle of Little Muddy Creek, also known as the Lame Deer Fight, was fought on May 7–8, 1877, by United States soldiers and scouts against a village of Miniconjou Lakota.

The battle occurred near Little Muddy Creek in Montana Territory, near present-day Lame Deer, Rosebud County.

On the Tongue River, Indian scouts found a trail heading west to Rosebud Creek, and Miles followed with his command of 471 officers and enlisted men.

Lame Deer grabbed his weapon on the ground and fired it at Miles, the bullet just missing him and killing his orderly, Private Charles Shrenger.

Companies F, G, and L of the 2nd Cavalry then attacked the small and defenseless Indian village, destroying it and capturing about 450 horses, killing half of them.
