Huguenot were any of the Protestants in France in the 16th and 17th centuries, many of whom suffered severe persecution for their faith.

Huguenots were French Protestants who held to the Reformed, or Calvinist, tradition of Protestantism. The term has its origin in early-16th-century France. It was frequently used in reference to those of the Reformed Church of France from the time of the Protestant Reformation. By contrast, the Protestant populations of eastern France, in Alsace, Moselle, and Montbéliard were mainly German Lutherans.

On the eve of the St. Bartholomew's Day massacre in 1572, the Huguenot community included as much as 10% of the French population. By 1600 it had declined to 7–8%, and was reduced further after the return of severe persecution in 1685 under Louis XIV's Edict of Fontainebleau.

The Huguenots were believed to be concentrated among the population in the southern and western parts of the Kingdom of France. As Huguenots gained influence and more openly displayed their faith, Catholic hostility grew. A series of religious conflicts followed, known as the French Wars of Religion, fought intermittently from 1562 to 1598.

The Huguenots were led by Jeanne d'Albret, her son, the future Henry IV (who would later convert to Catholicism in order to become king), and the princes of Condé. The wars ended with the Edict of Nantes, which granted the Huguenots substantial religious, political and military autonomy.
