Cambodia Capital: Phnom Penh, Cambodia's Largest City
Phnom Penh is the capital of Cambodia. It is also Cambodia’s largest city, so the Cambodia capital city and the country’s largest urban center are the same place. This guide gives a direct answer first, then explains where Phnom Penh is located, why it matters politically, when it became the modern capital, and how to read population figures correctly.
What Is the Capital of Cambodia?
For readers asking “what is the capital of Cambodia,” the simple answer is Phnom Penh. The city is the national center for government, administration, and much of Cambodia’s urban life.
Direct Answer: Phnom Penh
Phnom Penh is the capital of Cambodia. It is also the country’s largest city, a point stated by the official Phnom Penh Capital Hall facts page.
Current official city information identifies Phnom Penh as Cambodia’s capital; no current split-capital arrangement is indicated. Other Cambodian cities have important roles, but they do not share the same current capital status.
Key Facts at a Glance
The table below summarizes the core facts for quick reference. Population should always be read with the boundary and year attached, because administrative-city counts and wider urban estimates can differ.
| Fact | Answer |
|---|---|
| Capital of Cambodia | Phnom Penh |
| Largest city status | Also Cambodia’s largest city |
| General location | South-central Cambodia |
| River setting | Near the Mekong, Tonle Sap, and Bassac river system |
| Modern capital period | Since the nineteenth century, commonly linked to the move from Oudong around 1865 or 1866 |
| Administrative population reference | 2019 General Population Census |
Where Phnom Penh Is Located
Phnom Penh’s location helps explain its national importance. The city sits inland rather than on the coast, and it is closely connected to Cambodia’s major river system.
South-Central Cambodia and the River Confluence
Phnom Penh lies in the south-central part of Cambodia. It is widely associated with the meeting area of the Mekong, Tonle Sap, and Bassac rivers, a setting often described through the local name Chaktomuk, meaning a four-face or four-arm river confluence.
This river position gives Phnom Penh a strong geographic identity. The rivers are not only map features; they have shaped settlement, trade, movement, and the city’s symbolic place in Cambodian life. It is best, however, not to reduce the city’s rise to one single geographic reason. Political history, royal authority, colonial-era development, and modern administration all helped define Phnom Penh’s role.
Map Context for International Readers
On a map of Cambodia, Phnom Penh is inland and south of the great Tonle Sap lake region. It is separate from Cambodia’s coastal destinations, and it is not the same place as the Angkor temple area near Siem Reap.
This distinction matters because many international readers first learn about Cambodia through Angkor, Siem Reap, or coastal travel. Siem Reap is a major tourism gateway, and Battambang is an important provincial city, but Phnom Penh is the national capital. It is the city most closely associated with central government, embassies, national institutions, and capital-level administration.
Political and Administrative Role of Phnom Penh
Phnom Penh is more than a name on a map. It is Cambodia’s main political and administrative center and also a local government area with its own municipal structure.
National Seat of Government
As the capital of Cambodia, Phnom Penh functions as the main seat of national government. National institutions, ministries, diplomatic activity, and major public offices are centered in the city. The Royal Palace is also in Phnom Penh, giving the capital an important symbolic connection to Cambodia’s monarchy.
For general readers, the key point is simple: Cambodia does not have one city for the official capital and another city for the everyday government center in the available current information. Phnom Penh is the practical and symbolic center of national administration.
Capital Municipality and Local Governance
Phnom Penh is also a capital municipality, meaning it has local administrative responsibilities as well as national importance. The municipal authority is Phnom Penh Capital Hall, whose official site presents city information, public services, and local administrative material through Phnom Penh Capital Hall.
Readers may see local terms such as khans and sangkats. In plain English, khans are urban districts, and sangkats are smaller commune-level administrative units within the city. These terms matter because population, service areas, and local governance are often counted by administrative boundaries, not by a visitor’s visual impression of the built-up city.
When Phnom Penh Became the Capital
Phnom Penh’s current role is modern, but it is part of a longer history of changing Cambodian political centers. The most relevant historical shift for today’s capital question is the move from Oudong to Phnom Penh in the nineteenth century.
From Oudong to Phnom Penh
Phnom Penh’s modern continuous role as Cambodia’s capital dates to the nineteenth century. Sources commonly connect this change with the move from Oudong to Phnom Penh around 1865 or 1866, depending on how the transition is dated.
Oudong was an important former royal center and is often described as a former Cambodian capital. Background summaries of Oudong identify it as a royal residence and capital before Phnom Penh became the enduring modern capital.
The exact year may be framed slightly differently in different historical summaries, but the main point is clear: Phnom Penh replaced Oudong as the long-term modern capital of Cambodia in the nineteenth century.
Earlier Capitals in Cambodian History
Cambodia had earlier political centers before Phnom Penh. The Angkor-era context is especially important in Cambodian history, and the Angkor region is known worldwide for its monuments and historical importance.
However, historic importance is not the same as current capital status. Angkor and Oudong help explain Cambodia’s past, but Phnom Penh is the present-day capital. This distinction prevents confusion for readers who know Cambodia mainly through Angkor Wat or other historic sites.
Population and Urban Scale of Phnom Penh
Population figures for Phnom Penh can vary because different sources use different boundaries. The safest way to read a number is to ask whether it refers to the administrative municipality, the built-up urban area, or a wider metropolitan estimate.
Administrative City Population
The 2019 General Population Census is the main official reference for Cambodia’s population counts. The National Institute of Statistics census reported about 2.28 million people in Phnom Penh’s administrative area in 2019.
This figure refers to the municipality as counted in the census. It should not automatically be treated as the same as every urban-area or metropolitan estimate. When comparing Phnom Penh with other cities, keep the census boundary and reference year attached to the number.
Urban and Metropolitan Figures Need Careful Wording
Broader urban or metropolitan figures can be higher than an administrative-city count. This can happen when a source includes surrounding built-up areas, commuter zones, or nearby settlements that are closely connected to the capital.
For that reason, unsourced current-year estimates should be treated carefully. If a source gives a 2025 or future population number, check whether it is an official census figure, a projection, or a private estimate. The main reliable takeaway is that Phnom Penh is Cambodia’s largest urban center, while exact population totals depend on the definition used.
How Phnom Penh Compares with Other Cambodian Cities
Several Cambodian cities are important for culture, tourism, commerce, and provincial administration. None of them replaces Phnom Penh as the national capital.
Phnom Penh Versus Siem Reap and Battambang
Phnom Penh is Cambodia’s capital and largest city. Siem Reap is widely known as the gateway to the Angkor temple area, and Battambang is an important provincial city in the northwest. These cities matter, but they serve different roles.
The comparison is useful because international readers may be more familiar with Siem Reap than with Phnom Penh. If the question is “Cambodia capital” or “capital of Cambodia,” the answer is still Phnom Penh, not Siem Reap, Battambang, or Angkor.
Current Capital Status and No Verified Relocation Plan
Current available sources identify Phnom Penh as Cambodia’s capital. The provided official city information does not show a verified capital relocation or split-capital plan.
Future speculation should be separated from current reality. Unless a current official source states otherwise, Phnom Penh remains Cambodia’s current and practical capital, as well as its largest city.
Conclusion: The Capital of Cambodia in Summary
Phnom Penh is the capital of Cambodia and also the country’s largest city. It lies in south-central Cambodia near the Mekong, Tonle Sap, and Bassac river system, and it serves as the country’s main political and administrative center.
The city’s modern capital role is usually linked to the nineteenth-century move from Oudong. For population, use the 2019 census as the key official reference for the administrative municipality, and treat wider urban or metropolitan figures as separate estimates unless their boundaries are clearly explained.
