Laos Cities by Population 2026

Laos Overview

The largest city in Laos is Vientiane, with a population of 680,798 people.

The Southeast Asian country of Laos is known for its mountains, French colonial architecture and Buddhist monasteries. This is reflected in its capital city of Vientiane, which is home to European-style boulevards and many buildings from the colonial period, as well as Buddhist temples such as the sixteenth-century Pha That Luang, the national symbol of Laos and an icon of Buddhism. Vientiane, which is situated on the banks of the Mekong River near the border with Thailand has a population of 680.8K. It functions as the economic and administrative capital of the country.

Pakse, located in the southern province of Champasak, is the second-largest city in Laos with around 81.7K residents. Until it was unified with the rest of Laos in 1946, the city was the capital of the Kingdom of Champasak. Since the 1970s and the end of the Laotian Civil War, Pakse has become an increasingly important economic power within the country.
