Austria is a predominantly mountainous country in Central Europe, approximately between Germany, Italy and Hungary. It has a total area of .

Austria shares national borders with Switzerland (a non-European Union member state, which it borders for 158 km, or 98 mi) and the principality of Liechtenstein (also a non-EU member state, of which it borders for 34 km or 21 mi) to the west, Germany (801 km or 497 mi) and the Czech Republic (402 km or 249 mi) and Slovakia (105 km or 65 mi) to the north, Hungary to the east (331 km or 205 mi), and Slovenia (330 km or 185 mi) and Italy (404 km or 251 mi) to the south (total: 2,534 km or 1,574 mi).

The westernmost third of the somewhat pear-shaped country consists of a narrow corridor between Germany and Italy that is between wide. The rest of Austria lies to the east and has a maximum north–south width of . The country measures almost in length, extending from Lake Constance (German Bodensee) on the Austrian-Swiss-German border in the west to the Neusiedler See on the Austrian-Hungarian border in the east. The contrast between these two lakes – one in the Alps and the other a typical steppe lake on the westernmost fringe of the Hungarian Plain – illustrates the diversity of Austria's landscape.

Seven of Austria's nine federal states have long historical traditions predating the establishment of the Republic of Austria in 1918: Upper Austria, Lower Austria, Styria, Carinthia, Salzburg, Tyrol, and Vorarlberg. The states of Burgenland and Vienna were established after World War I. Most of Burgenland had been part of the Kingdom of Hungary, but it had a predominantly German-speaking population and hence became Austrian. Administrative and ideological reasons played a role in the establishment of Vienna as an independent state. Vienna, historically the capital of Lower Austria, was a socialist stronghold, whereas Lower Austria was conservative, and both socialists and conservatives wanted to consolidate their influence in their respective states. Each state has a state capital with the exception of Vienna, which is a state in its own right in addition to being the federal capital. In Vienna, the City Council and the mayor function as a state parliament (Landtag) and state governor (Landeshauptmann), respectively.

Physical geography

Landform regions

Austria may be divided into three unequal geographical areas. The largest part of Austria (62%) is occupied by the relatively young mountains of the Alps, but in the east, these give way to a part of the Pannonian plain, and north of the river Danube lies the Bohemian Forest, an older, but lower, granite mountain range.

River Danube The Danube has its source near Donaueschingen in southwestern Germany and flows through Austria before emptying into the Black Sea. It is the only major European river that flows eastwards, and its importance as an inland waterway has been enhanced by the completion in 1992 of the Rhine-Main-Danube Canal in Bavaria, which connects the rivers Rhine and Main with the Danube and makes barge traffic from the North Sea to the Black Sea possible.

The major rivers north of the watershed of the Austrian Alps (the Inn in Tyrol, the Salzach in Salzburg, and the Enns in Styria and Upper Austria) are direct tributaries of the Danube and flow north into the Danube valley, whereas the rivers south of the watershed in central and eastern Austria (the Gail and Drau rivers in Carinthia and the Mürz and Mur in Styria) flow south into the drainage system of the Drau, which eventually empties into the Danube in Serbia. Consequently, central and eastern Austria are geographically oriented away from the watershed of the Alps: the provinces of Upper Austria and Lower Austria toward the Danube and the provinces of Carinthia and Styria toward the Drau.

The Alps Three major ranges of the Alps – the Northern Calcareous Alps, Central Alps, and Southern Calcareous Alps – run west to east through Austria. The Central Alps, which consist largely of a granite base, are the largest and highest ranges in Austria. The Central Alps run from Tyrol to approximately the Styria-Lower Austria border and include areas that are permanently glaciated in the Ötztal Alps on the Tyrolean–Italian border and the High Tauern in East Tyrol and Carinthia. The Northern Calcareous Alps, which run from Vorarlberg through Tyrol into Salzburg along the German border and through Upper Austria and Lower Austria toward Vienna, and the Southern Calcareous Alps, on the Carinthia-Slovenia border, are predominantly limestone and dolomite. At 3,797 m, Großglockner is the highest mountain in Austria. As a general rule, the farther east the Northern and Central Alps run, the lower they become. The altitude of the mountains also drops north and south of the central ranges.

As a geographic feature, the Alps literally overshadow other landform regions. Just over 28% of Austria is moderately hilly or flat: the Northern Alpine Foreland, which includes the Danube Valley; the lowlands and hilly regions in northeastern and eastern Austria, which include the Danube Basin; and the rolling hills and lowlands of the Southeastern Alpine Foreland. The parts of Austria that are most suitable for settlement – that is, arable and climatically favorable – run north of the Alps through the provinces of Upper Austria and Lower Austria in the Danube Valley and then curve east and south of the Alps through Lower Austria, Vienna, Burgenland, and Styria. Austria's least mountainous landscape is southeast of the low Leithagebirge, which forms the southern lip of the Vienna Basin, where the steppe of the Hungarian Plain begins.

Bohemian Forest (mountain range) The granite massif of the Bohemian Forest (known in German as the Böhmerwald), a low mountain range with bare and windswept plateaus and a harsh climate, is located north of the Danube Valley and covers the remaining 10% of Austria's area. Notable is the Manhartsberg a granite ridge which separates Waldviertel from Weinviertel.

Forests In Austria forest cover is around 47% of the total land area, equivalent to 3,899,150 hectares (ha) of forest in 2020, up from 3,775,670 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 2,227,500 hectares (ha) and planted forest covered 1,671,500 hectares (ha). Of the naturally regenerating forest 2% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 23% of the forest area was found within protected areas. For the year 2015, 18% of the forest area was reported to be under public ownership, 82% private ownership and 0% with ownership listed as other or unknown.

Human geography

Land-use patterns in Austria change from Alpine to non-Alpine regions. Approximately one-tenth of Austria is barren or unproductive, that is, extremely Alpine or above the tree line. Just over 40% of Austria is covered by forests, the majority of which is in Alpine regions. Less than one-fifth of Austria is arable and suitable for conventional agriculture. The percentage of arable land in Austria increases in the East as the country becomes less alpine. More than one-fifth of Austria is pasture and meadow located at varying altitudes. Almost half of this grassland consists of high Alpine pastures.

Historically, high Alpine pastures have been used during the summer for grazing dairy cattle, thus making space available at lower altitudes for cultivating and harvesting fodder for winter. Many of the high pastures are at altitudes of more than 1,000 m.

Although agriculture in mountainous areas was at one time economically viable, in recent decades it has survived only with the help of extensive subsidies.

The Alps make many areas of Austria uninhabitable. Austria's so-called areas of permanent settlement – regions that are cultivated, continuously inhabited, and used for transportation, but do not include forests, Alpine pastures, or barren land – cover only 40% or 35,000 km2 of the country. The great majority of the area of permanent settlement is in the Danube valley and the lowlands or hilly regions north, east, and south of the Alps, where approximately two-thirds of the population lives.

In the country's predominantly Alpine provinces, most of the population live in river valleys: Bregenz on the shores of Lake Constance in Vorarlberg; Innsbruck on the river Inn in Tyrol; Salzburg on the river Salzach in Salzburg; and Klagenfurt on the Wörthersee lake in Carinthia. The higher the Alps are, the less inhabitable they become in terms of soil, microclimate, and vegetation. Conversely, the lower and broader the Alpine valleys are, the more densely populated they become.

Tyrol illustrates most clearly the relationship between Alpine geography and habitation. As the most mountainous province (less than 3% of the land is arable), it is the most sparsely inhabited, with an area of permanent settlement of only 15%.

Because of the Alps, the country as a whole is one of the least densely populated states of Western and Central Europe. With ninety-three inhabitants per square kilometre, Austria has a population density similar to that of the former Yugoslavia.

Austria's national borders and geography have corresponded very little. Since the fall of the Western Roman Empire, the Alps and the Danube have not served to mark political boundaries. Even within Austria, provincial borders were only occasionally set by the ranges and ridges of the Alps.

Although the Alps did not mark political boundaries, they often separated groups of people from one another. Because in the past the Alps were impassable, inhabitants isolated in valleys or networks of valleys developed distinct regional subcultures. Consequently, the inhabitants of one valley frequently maintained dialects, native or traditional dress, architectural styles, and folklore that substantially differed from those of the next valley. Differences were great enough that the origins of outsiders could easily be identified. However, mass media, mobility, prosperity, and tourism have eroded the distinctness of Alpine regional subcultures to a great extent by reducing the isolation that gave them their particular character.

Despite the Alps, Austria has historically been a land of transit. The Danube valley, for centuries Central Europe's aquatic link to the Balkan Peninsula and the "Orient" in the broadest sense of the word, has always been an avenue of east–west transit. However, Europe's division into two opposing economic and military blocs after World War II diminished Austria's importance as a place of transit. Since the opening of Eastern Europe in 1989, the country has begun to re-assume its historical role. By the early 1990s, it had already experienced a substantial increase in the number of people and vehicles crossing its eastern frontiers.
