Thurgau (German: [ˈtuːrɡaʊ] ^ⓘ; French: Thurgovie; Italian: Turgovia; Romansh: Turgovia), anglicized as Thurgovia, and formally^[4] as the Canton of Thurgau, is one of the 26 cantons forming the Swiss Confederation. It is composed of five districts. Its capital is Frauenfeld.

Thurgau is part of Eastern Switzerland. It is named after the river Thur, and the name Thurgovia was historically used for a larger area, including part of this river's basin upstream of the modern canton. The area of what is now Thurgau was acquired as subject territories by the cantons of the Old Swiss Confederacy from the mid 15th century. Thurgau was first declared a canton in its own right at the formation of the Helvetic Republic in 1798.

The population, as of December 2020, is 282,909.^[2] In 2007, there were a total of 47,390 resident foreigners, constituting 19.9% of the population.^[5]

In prehistoric times the lands of the canton were inhabited by people of the Pfyn culture along Lake Constance. During Roman times the canton was part of the province Raetia until 450, when Alemanni settled on the lands.

In the sixth century, Thurgovia became a Gau of Francia as part of Alamannia, passing to the Duchy of Swabia in the early 10th century. At this time, Thurgovia included not just what is now the canton of Thurgau, but also much of the territory of the modern canton of St. Gallen, the Appenzell and the eastern parts of the canton of Zürich.

The most important cities of Thurgovia in the early medieval period were Konstanz as the seat of the bishop and St. Gallen for the Abbey of Saint Gall.

The dukes of the House of Zähringen and the counts of the Kyburg family took over much of the land in the High Middle Ages. The town of Zürich was part of the Thurgau until it became reichsunmittelbar in 1218.^{[dubious – discuss]} When the Kyburg dynasty became extinct in 1264 the House of Habsburg took over that land.

The Old Swiss Confederacy allied with ten freed bailiwicks of the former Toggenburg seized the lands of the Thurgau from the Habsburgs in 1460, and it became a subject territory of seven Swiss cantons (Zurich, Lucerne, Uri, Schwyz, Unterwalden, Zug and Glarus).

During the Protestant Reformation in Switzerland, both the Catholic and emerging Reformed parties sought to swing the subject territories, such as the Thurgau, to their side. In 1524, in an incident that resonated across Switzerland, local peasants occupied the cloister of Ittingen in the Thurgau, driving out monks, destroying documents, and devastating the wine-cellar. Between 1526 and 1531, most of the Thurgau's population adopted the new Reformed faith spreading from Zurich; Zurich's defeat in the 1531 Second War of Kappel ended Reformed predominance. Instead, the First Peace of Kappel protected both Catholic and Reformed worship, though the provisions of the treaty generally favored the Catholics, who also made up a majority among the seven ruling cantons. Religious tensions over the Thurgau were an important background to the First War of Villmergen (1656), during which Zurich briefly occupied the Thurgau.

In 1798 the land became a canton for the first time as part of the Helvetic Republic. In 1803, as part of the Act of Mediation, the canton of Thurgau became a member of the Swiss confederation. The cantonal coat of arms was designed in 1803, based on the coat of arms of the Kyburg family, which ruled the Thurgau in the 13th century, changing the background to green-and-white, at the time considered "revolutionary" colours (c.f. tricolour); as the placement of a yellow (or) charge on white (argent) is a violation of heraldic principles, there have been suggestions to modify the design, including a 1938 suggestion to use a solid green field divided by a diagonal white line, but they were unsuccessful.

The current cantonal constitution of Thurgau dates from 1987.

To the north the canton is bound by the Lake Constance across which lies Germany (Baden-Württemberg and Bavaria) and Austria (Vorarlberg). The Rhine creates the border in the northwest. To the south lies the canton of St. Gallen; to the west lie the cantons of Zürich and Schaffhausen.

The area of the canton is 991 km² (383 sq mi) and commonly divided into three hill masses. One of these stretches along Lake Constance in the north. Another is further inland between the Thur and the river Murg. The third one forms the southern border of the canton and merges with the Hörnli mountain in the pre-Alps.

The population of the canton (as of 31 December 2020) is 282,909.^[2] The canton is mostly German speaking. The population (as of 2000) is split between Protestants (45%) and Roman Catholics (36%).^[6]
