Charles Mills (September 1, 1840 – unknown) was a U.S. sailor stationed aboard the USS Minnesota during the American Civil War.

Mills volunteered for service in the U.S. Navy and was assigned to the Union steam frigate USS Minnesota.

On January 15, 1865 the North Carolina Confederate stronghold of Fort Fisher was taken by a combined Union storming party of sailors, marines, and soldiers under the command of Admiral David Dixon Porter and General Alfred Terry.

Landing on the beach with the assaulting party from his ship, Seaman Mills charged up to the palisades and, when more than two thirds of the men became seized with panic and retreated on the run, risked his life to remain with a wounded officer.

With the enemy concentrating his fire on the group, he waited until after dark before assisting the wounded man from the field.
