Mule Ear Peaks are two summits in Brewster County, Texas, United States.

Mule Ear Peaks is part of the Chisos Mountains and is set in the Chihuahuan Desert where it is an iconic landmark in Big Bend National Park.

[7] Any scant precipitation runoff from the peak's slopes drains into Smoky Creek which empties into the Rio Grande six miles to the south-southwest.

Topographic relief is significant as the summit rises 1,080 feet (329 m) above Smoky Creek in 0.35 mile (0.56 km).

The mountain's descriptive toponym has been officially adopted by the United States Board on Geographic Names,[3] and has been featured in publications since at least 1907.
