Egnach is a municipality of the district of Arbon in the canton of Thurgau in Switzerland.

[3] By the 9th century it appears to have belonged to the Bishopric of Constance and was part of the upper Bailiwick of Arbon.

The Abbey of Saint Gall acquired land in Egnach, which led to competing legal claims between abbot and bishop (which were settled in 854).

During the Late Middle Ages it was a regional administrative center for lands of the Bishops of Constance.

After the conquest of Thurgau by the Swiss Confederation in 1460, the new rulers replaced all the Bishop's representatives.

Already in the 18th century the region was home to numerous orchards, which caused the area around Egnach to be known as Mostindien or Cider.

Various branches of textile production flourished in Egnach, in the early 19th century.

In spite of some industrial and residential areas, the village retains its rural character.
