The German name of the canton, , translates as the "Grey Leagues", referring to the canton's origin in three local alliances, the Three Leagues. The other native names also refer to the Grey League: in Sutsilvan, in the other forms of Romansh, and in Italian. is the Latin name for the area. The Alpine ibex is the canton's heraldic symbol.

The largest and easternmost canton of Switzerland, it is also one of the three large southern Alpine cantons, along with Valais and Ticino. It is the most diverse canton in terms of natural and cultural geography, as it encompasses both sides of the Alps and several natural and cultural regions. The diversity of the canton is often compared to that of Switzerland as a whole and warrants it the name of "Little Switzerland". The Grisons is bordered by four cantons as well as Austria, Italy and Liechtenstein.

The state is the only trilingual canton of Switzerland. It is also the only one where Romansh, Switzerland's fourth national language, has official status. Romansh language and culture is an important part of local identity. In the canton had a population of . It is the least densely populated canton of Switzerland. The only sizable city in the canton is Chur, as the majority of the population lives in mountainous areas, including some of the most remote valleys of the country. One of the birthplaces of winter sports, the canton is a major tourist destination year-round, including a large number of Alpine resort towns, notably Davos and St. Moritz. The canton is also renowned for its extensive narrow-gauge railway network, operated by the Rhaetian Railway, and linking the capital with most valleys of the Grisons.

Formerly occupied by the Rhaeti, most of the lands of the canton became part of the Roman province called Raetia, which was established in 15 BC, with ''Curia'', a settlement dating back to the Pfyn culture, as capital city. The area later became part of the lands of the diocese of Chur. The late middle ages saw the foundation of the League of God's House, the Grey League and the League of the Ten Jurisdictions. In 1471 an alliance gave birth to the Three Leagues, and before the end of the 15th century, the latter became an ally of the Old Swiss Confederacy. In 1803 the Three Leagues finally became one of the cantons of the Confederation.

Geography and climate

The Grisons is Switzerland's largest and at the same time easternmost canton. Its geography, essentially marked by the Alps, is complex and encompasses a wide range of climates and ecosystems. It is one of the three large southern Alpine cantons, along with Ticino and Valais, which include regions on the south side of the Alps. But in contrast to those (and all other cantons), it fully extends on both sides of the great Alpine barrier, from the northern plains at Maienfeld to the southern plains at Roveredo. However, a large portion of the canton is neither clearly north nor south of the Alps, it is the Engadin (the "garden of the Inn"), a large inner Alpine valley oriented towards eastern Europe. Therefore there are parts of this canton in four of the five drainage basins of the country. The north of the canton is drained by the Rhine (ending in the North Sea), the south by the Po and Adige through several affluents (Mediterranean Sea), and the Engadin by the Danube through the Inn (Black Sea).Topographic map of the Grisons

The Grisons lies fully within the Alps, with elevations above sea-level ranging from . It is both one of the highest and lowest cantons, and the second-highest when considering mean elevation. As a consequence, its topography is extremely rugged and many of the highest settlements in the country (and Europe) are found there, notably in the Upper Engadin. The mountains are numerous; well over 1,000 summits are in the canton. The highest is Piz Bernina, closely followed by numerous peaks in the homonymous range. Other prominent mountains are Piz Russein, Piz Kesch, Calanda, Aroser Rothorn and Rheinwaldhorn, see list of mountains of Graubünden for a more exhaustive list. The canton includes numerous subranges of the Alps other than the Bernina. These are the Albula, the Bregaglia, the Glarus
