Oriskany Battlefield State Historic Site is a historic site in Oneida County, New York, United States that marks the Battle of Oriskany, fought in 1777 during the American Revolution, one of the bloodiest engagements of the war.

An obelisk, with plaques at the base commemorating the battle and its participants, is the central feature of the site.

Patriot militia General Nicholas Herkimer, leading a relief column to the besieged Fort Stanwix, was ambushed in a ravine by Iroquois chief Joseph Brant, leading a mixed group of Iroquois and Tories.

After sustaining high casualties in the number of native War Chiefs, and a heavy downpour the British forces withdrew, leaving the Tryon County militia in possession of the field.
