The largest city in Romania is Bucharest, with roughly 1.8 million residents, followed by Cluj-Napoca and Timișoara (each around 320,000), Iași (290,000), Constanța (280,000), Craiova (270,000), Brașov (250,000), Galați (250,000), Ploiești (210,000) and Oradea (200,000). Together these ten cities form the urban backbone of a country of roughly 19 million people, anchoring its economy, universities and cultural life.
The Ten Largest Romanian Cities
Romania's largest cities are spread across every corner of the country, from the Danube ports of the southeast to the Transylvanian heartland in the centre and west. Bucharest dominates so completely that it is more than five times the size of the next-largest city.
- 1. Bucharest — ~1.8 million (capital, southern Wallachia)
- 2. Cluj-Napoca — ~320,000 (Transylvania)
- 3. Timișoara — ~320,000 (Banat, west)
- 4. Iași — ~290,000 (Moldavia, northeast)
- 5. Constanța — ~280,000 (Black Sea coast)
- 6. Craiova — ~270,000 (Oltenia, southwest)
- 7. Brașov — ~250,000 (central Transylvania)
- 8. Galați — ~250,000 (Danube, east)
- 9. Ploiești — ~210,000 (Wallachia, near Bucharest)
- 10. Oradea — ~200,000 (Crișana, northwest)
Bucharest: The Capital That Towers Above the Rest
Bucharest is in a league of its own. As the national capital it concentrates government, finance, media and the largest share of foreign investment in the country, and its wider metropolitan area pushes the population well above two million. The city earned the nickname "Little Paris" in the early 20th century thanks to its elegant Belle Époque boulevards and an Arcul de Triumf modelled on the Parisian arch. It is also home to the Palace of the Parliament, one of the heaviest and largest administrative buildings on Earth. Because no other Romanian city comes close in size, the country is sometimes described as having a single dominant "primate city."
The Transylvanian and Western Powerhouses
After the capital, the next tier of cities is remarkably close in size. Cluj-Napoca is the unofficial capital of Transylvania and a fast-growing technology and university centre, often cited as one of Romania's most dynamic economies. Timișoara, in the western Banat region, is proud of its multicultural heritage and its role as the city where the 1989 revolution began; it was a European Capital of Culture in 2023. Oradea, near the Hungarian border, is celebrated for one of the largest concentrations of Art Nouveau architecture in the region. These western cities benefit from proximity to Central Europe and strong cross-border trade links.
The Eastern and Coastal Cities
Iași, in the northeast region of Moldavia, is one of Romania's oldest cultural and academic centres, home to the country's first university. Constanța is the largest city on the Black Sea and hosts Romania's main seaport — one of the biggest on the entire Black Sea — alongside the popular Mamaia beach resort. Further inland, Galați is a major Danube port and steel-producing centre, while Brașov, ringed by the Carpathian Mountains, blends Saxon medieval architecture with year-round tourism. Craiova serves as the economic hub of the southwestern Oltenia region, and Ploiești, just north of Bucharest, grew up around Romania's historic oil industry.
How Romania's Cities Compare
Romania's urban pattern is shaped by history as much as geography. Many of these cities trace their origins back centuries or even millennia — Constanța descends from the ancient Greek colony of Tomis, and several Transylvanian towns were founded by German-speaking Saxon settlers in the Middle Ages. While Bucharest keeps growing, several other large cities have seen populations dip slightly as residents move to suburbs or work abroad, a trend common across post-1990 Central and Eastern Europe. Even so, the top ten cities account for a large slice of Romania's urban population and concentrate most of its jobs, students and infrastructure.

Three Historic Regions, Three Different Inheritances
Modern Romania was assembled from three principalities with separate histories, and the cities on this list still reflect them. Wallachia in the south, with Bucharest and Craiova, and Moldavia in the north-east, with Iasi, were Ottoman tributaries for centuries.
Transylvania, in the centre and west, was under Hungarian and then Habsburg rule until 1918, and its cities look it. Cluj-Napoca, Brasov, Sibiu and Timisoara have central European squares, Gothic and baroque churches and German or Hungarian names still in use: Klausenburg, Kronstadt, Hermannstadt, Temeswar.
Sibiu and Brasov were founded by Transylvanian Saxons, German settlers invited from the twelfth century, whose fortified churches across the region are a UNESCO World Heritage Site. Most of that community emigrated to Germany after 1989.
Bucharest Was Rebuilt Around One Building
In the 1980s Nicolae Ceausescu demolished roughly a fifth of historic Bucharest, including churches, hospitals and the homes of tens of thousands of people, to build the Centrul Civic and the Palace of the Parliament.
That building is the heaviest in the world and among the largest by floor area, with over a thousand rooms, built with Romanian materials and labour at enormous cost while the country was exporting food to pay foreign debt.
Some churches were saved by being physically moved on rails to sites behind new apartment blocks, an engineering operation carried out by Eugeniu Iordachescu that preserved several buildings that would otherwise have gone.
Timisoara Started the Revolution
The Romanian revolution of December 1989 began in Timisoara, with protests over the removal of a Hungarian pastor that grew into a general uprising. Within days it had spread to Bucharest, and Ceausescu was executed on 25 December.
Timisoara has a history of being first: it was among the earliest cities in Europe to have electric street lighting, in 1884, and it holds a large baroque square laid out under Habsburg rule.
It was a European Capital of Culture in 2023, and it sits in the Banat, a region historically shared among Romanians, Hungarians, Germans and Serbs, which gives the city an unusually mixed character even by Romanian standards.
The Cities Are Shrinking Faster Than Almost Anywhere
Romania's population has fallen by several million since 1990, one of the steepest declines of any country not at war. Emigration is the main cause: millions left for Italy, Spain, Germany and the United Kingdom, particularly after EU accession in 2007.
Most cities on this list are smaller than they were in 1992, and several have lost a fifth or more of their residents. Bucharest, Cluj-Napoca and Timisoara have fared better by drawing people internally, and Cluj in particular has grown on the back of a large technology sector.
The demographic hole is now a labour shortage, and Romania has begun importing workers from South and South-East Asia to fill jobs in construction and services, which is a reversal few expected a decade ago.
The Danube and the Delta
The Danube forms much of Romania's southern border and reaches the Black Sea through the Danube Delta, the largest and best-preserved river delta in Europe and a UNESCO World Heritage Site holding the greatest concentration of bird colonies on the continent.
Constanta, on the coast, is the country's main port and the largest on the Black Sea, and it is also the oldest continuously inhabited city in Romania, founded as the Greek colony of Tomis. Ovid was exiled there in the year 8 and complained about it at length.
Galati and Braila, upriver, are Danube ports that handled the nineteenth-century grain trade, and both have lost population heavily since their shipyards and industry contracted.
Cluj Became a Technology City
Cluj-Napoca has grown while most Romanian cities have shrunk, and the reason is software. The city has the country's largest concentration of technology employment outside Bucharest, built on its universities and on outsourcing contracts that arrived in the 2000s.
It is also the historic centre of Hungarian Transylvania. Around a sixth of the city's residents are ethnic Hungarians, Babes-Bolyai University teaches in Romanian, Hungarian and German, and Matthias Corvinus, king of Hungary, was born there in 1443.
The Napoca in its name was added in 1974, restoring the Roman settlement's name to underline continuity of Romanian presence in Transylvania, which is a good example of how the region's contested history shows up in ordinary signage.
Common Questions About Romanian Cities
What is the largest city in Romania?
Bucharest is by far the largest city in Romania, with around 1.8 million residents in the city proper and over two million in its metropolitan area. It is the national capital and the country's main economic and cultural centre.
What is the second-largest city in Romania?
Cluj-Napoca and Timișoara are essentially tied for second place, each with roughly 320,000 residents. Cluj-Napoca is the leading city of Transylvania, while Timișoara anchors the western Banat region.
How many large cities does Romania have?
Romania has one very large city (Bucharest) and a cluster of mid-sized cities in the 200,000–320,000 range. Beyond the top ten, several other cities such as Brăila, Arad and Pitești also exceed 100,000 people.
Which Romanian city is on the Black Sea?
Constanța is Romania's main Black Sea city and largest port, with about 280,000 residents. It is a major shipping hub and a popular summer destination thanks to the neighbouring Mamaia resort. Test your knowledge of world cities with our geography games.
Is Transylvania part of Romania?
Yes, and has been since 1918, confirmed by the Treaty of Trianon in 1920. It was previously under Hungarian and Habsburg rule, which is why its cities have German and Hungarian names alongside Romanian ones and a noticeably central European appearance.
Which Romanian city has grown recently?
Cluj-Napoca, largely on the back of its technology sector and universities, and Bucharest and Timisoara to a lesser extent. Most other cities on this list have lost population since 1990 through emigration and falling birth rates.
