The largest cities in Austria by population are Vienna (around 1.9 million), Graz (about 290,000), Linz (about 210,000), Salzburg (about 160,000), Innsbruck (about 130,000), Klagenfurt (about 100,000), Villach, Wels, St. Pölten and Dornbirn (each roughly 50,000–60,000). Together these ten cities anchor a country of roughly 9 million people, and the gap between them tells a striking story: Vienna alone holds more residents than the next nine cities combined.
The Ten Largest Austrian Cities
Austria is a relatively small Alpine nation, and its urban hierarchy is dominated by a single giant. Here are the ten largest cities ranked by population:
- Vienna (Wien) — ~1,900,000
- Graz — ~290,000
- Linz — ~210,000
- Salzburg — ~160,000
- Innsbruck — ~130,000
- Klagenfurt am Wörthersee — ~100,000
- Villach — ~63,000
- Wels — ~62,000
- St. Pölten — ~57,000
- Dornbirn — ~50,000
The drop-off is dramatic. Vienna is roughly six and a half times larger than Graz, the second city, a degree of dominance known as primacy that is unusual even among small European states.
Vienna: A Capital That Towers Over the Rest
Vienna is both the national capital and a federal state in its own right. With about 1.9 million residents in the city proper and well over 2 million in its metropolitan area, it is one of the largest cities in Central Europe. For centuries it was the seat of the Habsburg monarchy and the capital of the sprawling Austro-Hungarian Empire, which left it with grand boulevards, imperial palaces such as Schönbrunn and Hofburg, and a world-renowned tradition of classical music tied to Mozart, Beethoven and Strauss. Today Vienna is regularly ranked among the most livable cities on Earth, praised for its public transport, social housing and cultural life. It is the undisputed economic, political and intellectual heart of Austria.
Graz, Linz and Salzburg: The Regional Powerhouses
Graz, the capital of Styria, is the second-largest city with around 290,000 people. It is a major university town, home to a UNESCO-listed old town and a reputation as a hub for design and technology. Linz, capital of Upper Austria, sits on the Danube with roughly 210,000 residents; once known chiefly for heavy industry and steelmaking, it has reinvented itself as a UNESCO City of Media Arts. Salzburg, with about 160,000 people, is perhaps the most internationally famous of Austria's smaller cities — the birthplace of Mozart, the setting of The Sound of Music, and home to a baroque old town that draws millions of visitors and festival-goers each year.
Innsbruck and the Smaller Cities
Innsbruck, the Tyrolean capital with around 130,000 residents, is the alpine gateway of the group, framed by towering peaks and twice host to the Winter Olympics. Below it, the cities cluster closely in size. Klagenfurt in Carinthia hovers around the 100,000 mark beside the warm Wörthersee lake. Villach, Wels, St. Pölten and Dornbirn each sit in the 50,000–63,000 range. Notably, St. Pölten is the capital of Lower Austria — Austria's most populous province — even though it ranks only ninth among cities, a reminder that political importance and population size do not always align. Dornbirn, in the far-western Vorarlberg region, rounds out the top ten.
What the Rankings Reveal About Austria
Austria's settlement pattern reflects both its geography and its history. Much of the country is mountainous, so larger cities tend to grow in valleys, along the Danube, or on accessible plateaus. The overwhelming concentration in Vienna stems from its imperial past as the administrative center of a far larger realm. Each of the other cities, meanwhile, generally serves as the capital of one of Austria's nine federal states, giving the urban map a tidy regional logic. For travelers and learners alike, exploring these cities is a fast way to understand the whole country — see our austria country guide for more on the nation's geography, regions and culture.
Vienna Is Far Larger Than Everything Else
Vienna holds close to two million people; Graz, the second city, is around 300,000. That ratio is among the most lopsided in Europe, and the reason is imperial.
Vienna was the capital of the Habsburg monarchy, which at its height governed some fifty million people across central Europe. When the empire dissolved in 1918, Austria was left with a capital built for a realm ten times its size.
The phrase used at the time was that Austria had become a head without a body. Vienna's palaces, ministries, opera house and Ringstrasse were all built for that vanished state, which is why the city's grandeur is out of proportion to the modern country.
Red Vienna Built Housing That Still Stands
Between 1919 and 1934 Vienna's Social Democratic administration built large-scale municipal housing funded by progressive taxation, and the programme is still running in modified form.
Karl-Marx-Hof, completed in 1930, runs for more than a kilometre and contains over a thousand flats. It was fortified and fought over during the brief civil war of February 1934.
The consequence today is that roughly half of Vienna's population lives in municipal or subsidised housing, which is the highest proportion of any large European city and the main reason Vienna's rents are markedly lower than comparable capitals. It appears at or near the top of international quality-of-life rankings most years.
The Country Is Mostly Mountain
The Alps cover about two thirds of Austria, and the cities are strung along the valleys and the eastern lowlands. Innsbruck sits in the Inn valley surrounded by peaks and has hosted two Winter Olympics; Salzburg lies at the northern edge of the Alps on the Salzach.
Vienna, Linz and Graz are all in the flatter east and south-east, which is where the arable land and the industry are. The Danube runs through Linz and Vienna and was the Roman frontier, the limes, with Vindobona standing where Vienna's old town is now.
Salt gave Salzburg its name and its wealth, mined at Hallein and Hallstatt, where the mine has been worked for some seven thousand years and gave its name to an entire Iron Age culture.
Music Is an Export Industry
Vienna's association with classical music is not merely historical marketing. Haydn, Mozart, Beethoven, Schubert, Brahms, Bruckner, Mahler, Schoenberg, Berg and Webern all worked in the city, most of them for extended periods.
The Vienna Philharmonic's New Year's Day concert is broadcast to something in the region of ninety countries, and the Staatsoper stages more than fifty different productions a season, which is an unusually heavy repertory schedule.
Salzburg was Mozart's birthplace and runs a summer festival founded in 1920 that remains among the most significant in the world. The Sound of Music, filmed there, draws a category of visitor that Salzburg has learned to accommodate despite the film being largely unknown to Austrians.
A Neutral Country With a Diplomatic City
Austria declared permanent neutrality in 1955 as the condition for Soviet withdrawal, and Vienna subsequently became a hosting city for international organisations in the way Geneva had.
The Vienna International Centre, opened in 1979, houses the International Atomic Energy Agency and several UN bodies, and the city also hosts OPEC and the Organization for Security and Co-operation in Europe.
Its position during the Cold War, a western capital surrounded on three sides by the Eastern Bloc, made it a natural meeting point, and the Iranian nuclear negotiations and numerous arms-control talks have been held there since.
Coffee Houses Are Protected Heritage
The Viennese coffee house was added to UNESCO's national intangible cultural heritage list in 2011, described in the nomination as a place where time and space are consumed but only the coffee is found on the bill.
The institution dates from the late seventeenth century and became central to intellectual life: Freud, Trotsky, Klimt, Zweig and the logical positivists all worked in specific cafes, and several are still open under the same names.
The convention is that a single coffee buys a table for as long as you want it, with newspapers on wooden frames provided. The waiter's traditional slight brusqueness is treated as part of the offering rather than a failure of service.
Common Questions About Austrian Cities
What is the largest city in Austria?
Vienna is by far the largest city, with about 1.9 million residents in the city proper. It is also the national capital and a federal state, and its metropolitan area holds more than 2 million people.
What is the second-largest city in Austria?
Graz, the capital of the province of Styria, is the second-largest city with roughly 290,000 inhabitants — still less than a sixth of Vienna's population.
Is Salzburg or Innsbruck bigger?
Salzburg is bigger, with around 160,000 residents compared to Innsbruck's roughly 130,000. Both are famous tourist destinations, but Salzburg ranks fourth nationally while Innsbruck ranks fifth.
How many large cities does Austria have?
Only Vienna exceeds one million people, and just five cities surpass 100,000. Austria is a country of one major metropolis and many mid-sized regional centers, most of which serve as provincial capitals.
Why is Vienna so much bigger than the rest of Austria?
Because it was built as the capital of an empire of around fifty million people. When Austria-Hungary dissolved in 1918 the city kept its institutions and scale while the country shrank to under seven million.
Which is Austria's second city?
Graz, at roughly 300,000, followed by Linz, Salzburg and Innsbruck. All are under 300,000, which leaves Vienna around six times larger than any rival.
