Black Buttes is an extinct volcano in the Cascade Volcanic Arc in Washington, United States. Glacially eroded remnants of this volcano rise above the Deming Glacier, part of the glacier system of Mount Baker.[2]

The volcano was last active between 500,000 and 300,000 years ago.[3] Mount Baker, a much younger volcano, sits on top of lava erupted from Black Buttes Volcano. Mount Baker volcano is less than 140,000 years old.[3]
