Battery Rock is a limestone bluff located at Mile 860 of the Ohio River in Hardin County, Illinois, across from Caseyville, Kentucky.

The bluff also played a role in Confederate general Stovepipe Johnson's attack on riverboats in 1864.

During the attack, boats used the landing at Battery Rock as a safe harbor and a place to monitor the situation.

In addition, two Union recruiters from Kentucky used the bluff as a recruiting station in 1864, and either a Union garrison or a local defense force placed two cannons at the site; graffiti left by an Indiana regiment has also been found at the site.
