The Pennsylvania Dutch, also referred to as Pennsylvania Germans, are an ethnic group in Pennsylvania and other regions of the United States, predominantly in the Mid-Atlantic region of the nation. They largely descend from the Palatinate region of Germany, and settled in Pennsylvania during the 17th, 18th, and 19th centuries. While most were from the Palatinate region of Germany, a lesser number were from other German-speaking areas of Germany and Europe, including Baden-Württemberg, Hesse, Saxony, and Rhineland in Germany, the Netherlands, Switzerland, and the Alsace–Lorraine region of France.

The Fancy Dutch, also known as the High Dutch, and historically as the Pennsylvania High Germans, are the Pennsylvania Dutch who do not belong to Plain Dutch sects. Unlike the Amish, the conservative Dunkards, or Old Order Mennonites, they do not wear plain clothing, and they fight in wars. Many popularly associated characteristics of Pennsylvania Dutch culture, including spielwerk, hex signs, and other aspects of Pennsylvania Dutch art, music, and folklore, are derived from the Fancy Dutch. The tourism industry and mainstream media often erroneously attribute such contributions to the more conservative Plain Dutch, though they would reject these aspects of their more worldly Fancy counterparts.
