The Georgia Guidestones is a granite monument in Elbert County, Georgia, in the United States. A message clearly conveying a set of ten guidelines is inscribed on the structure in eight modern languages, and a shorter message is inscribed at the top of the structure in four ancient language scripts: Babylonian, Classical Greek, Sanskrit, and Egyptian hieroglyphs.

The structure is sometimes referred to as an "American Stonehenge". The monument is 19 feet 3 inches (5.87 m) tall, made from six granite slabs weighing 237,746 pounds (107,840 kg) in all. One slab stands in the center, with four arranged around it. A capstone lies on top of the five slabs, which are astronomically aligned. An additional stone tablet, which is set in the ground a short distance to the west of the structure, provides some notes on the history and purpose of the Guidestones.
