The Gnadenhutten massacre, also known as the Moravian massacre, is the killing of ninety-six Christian Lenape (Delaware) by colonial American militia from Pennsylvania on March 8, 1782 at the Moravian missionary village of Gnadenhutten, Ohio during the American Revolutionary War.

The site of the village has been preserved.

A reconstructed mission house and cooper's house are built here, and a monument to the dead is erected and dedicated a century later.

The burial mound is marked and has been maintained on the site.

The village site is listed on the National Register of Historic Places.
