The O'Shaughnessy Dam is located on the Scioto River near Dublin, Ohio, United States. The dam forms O'Shaughnessy Reservoir, which is a major source of drinking water for the city of Columbus.

The reservoir holds 6.3 billion US gallons over a surface area of 845 acres. The Columbus Zoo and Aquarium is located on the east bank of the reservoir, near the dam.
