[[Image:Wenro-Territorium um 1630.png|thumb|300px|The French missionaries monitoring first people in 1630s report the Wenro's territory was north and east of the Erie peoples, East of the Neutral people across the Niagara River and west of the Genesee River valley and the Genesee Gorge across which the Seneca people had their home.
Amerindian boundaries, such as they had use to understand, would likely have been defined along water courses, and ridgelines (i.e. Drainage divides, unlike the southern border approximated by the neat lines above.]] The Wenrohronon or the Wenro People, were a little-known Iroquoian Amerindian people of North America, originally residing in present-day western New York (and possibly fringe portions of northern & northwestern Pennsylvania) who were conquered by the Confederation of the Five Nations of the Iroquois in two decisive wars between 1638-1639 and 1643— probably as part of the Iroquois campaign against their likely relatives and abutting neighbors, the Neutral people which lived across the Niagara River. The Iroquois had discovered a secret, their winter attacks lead to advantageous campaigns allowing attritional defeats on both the larger Iroquoian confederacies, as it had against the numerous Huron.
The Tobacco people having fallen in 1650-1651 after a December 1649 sneak attack kicked off that phase of the Beaver Wars as the Iroquois rampaged westwards along the north shores of Lake Ontario after their defeat of the Huron in 1849. As had happened to the Huron peoples, the sudden unexpected winter attack led to disorganization and isolation of clan groups, and early losses of key towns by the Neutrals in the 1651-53 campaign by the warriors of the League of the Iroquois leading to eventual defeat and displacement (flight by whole villages) of first the Tobacco tribes, then the Neutral groups, as had happened to the Huron.
