The Wenrohronon or the Wenro People, are an Iroquoian Amerindian people of North America, originally residing in present-day western New York (and possibly fringe portions of northern and northwestern Pennsylvania) who are 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, who live across the Niagara River.

The Iroquois have 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 Tabacco people had 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 1649.

As had happened to the Huron peoples, the sudden unexpected winter attack leads 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.
