The Republic and Canton of Jura (officially in French: République et Canton du Jura), less formally the Canton of Jura or Canton Jura ( JOOR-ə, ZHOOR-ə; French: [ʒyʁa] ), is the newest (founded in 1979) of the 26 Swiss cantons, located in the northwestern part of Switzerland. The capital is Delémont . It shares borders with the canton of Basel-Landschaft , the Canton of Bern , the canton of Neuchatel, the Canton of Solothurn , and the French regions of Bourgogne-Franche-Comté and Grand Est.

The king of Burgundy donated much of the land that today makes up canton Jura to the bishop of Basel in 999. The area was a sovereign state within the Holy Roman Empire for more than 800 years. After the Treaty of Westphalia in 1648, the Jura had close ties with the Swiss Confederation.
