Laos, officially the Lao People's Democratic Republic, is the only landlocked country in Southeast Asia. At the heart of the Indochinese Peninsula, Laos is bordered by Myanmar and China to the northwest, Vietnam to the east, Cambodia to the southeast, and Thailand to the west and southwest. Its capital and largest city is Vientiane.
Evidence of modern human presence in the northern and central highlands of Indochina, which constitute the territories of the modern Laotian nation-state, dates back to the Lower Paleolithic. These earliest human migrants are Australo-Melanesians—associated with the Hoabinhian culture—and have populated the highlands and the interior, less accessible regions of Laos and all of Southeast Asia to this day. The subsequent Austroasiatic and Austronesian marine migration waves affected landlocked Laos only marginally, and direct Chinese and Indian cultural contact had a greater impact on the country.
This article concerns the systems of transportation in Laos. Laos is a country in Asia, which possesses a number of modern transportation systems, including several highways and a number of airports. As a landlocked country, Laos possesses no ports or harbours on the sea, and the difficulty of navigation on the Mekong means that this is also not a significant transport route.
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth-longest river and the third-longest in Asia with an estimated length of 4,909 km (3,050 mi) and a drainage area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. From its headwaters in the Tibetan Plateau, the river runs through Southwest China, Myanmar, Laos, Thailand, Cambodia, and southern Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between Tibet and Southeast Asia. The construction of hydroelectric dams along the Mekong in the 2000s through the 2020s has caused serious problems for the river's ecosystem, including the exacerbation of drought.
Lan Xang or Lancang was a Lao kingdom that held the area of present-day Laos from 1353 to 1707. For three and a half centuries, Lan Xang was one of the largest kingdoms in Southeast Asia. The kingdom is the basis for Laos's national historic and cultural identity.

Laos developed its culture and customs as the inland crossroads of trade and migration in Southeast Asia over millennia. As of 2012 Laos has a population of roughly 6.4 million spread over 236,800 km2, yielding one of the lowest population densities in Asia. Yet the country of Laos has an official count of over forty-seven ethnicities divided into 149 sub-groups and 80 different languages. The Lao Loum have throughout the country's history comprised the ethnic and linguistic majority. In Southeast Asia, traditional Lao culture is considered one of the Indic cultures.
The French protectorate of Laos was a French protectorate in Southeast Asia of what is today Laos between 1893 and 1953—with a brief interregnum as a Japanese puppet state in 1945—which constituted part of French Indochina. It was established over the Siamese vassal, the Kingdom of Luang Phrabang, following the Franco-Siamese crisis of 1893. It was integrated into French Indochina and in the following years further Siamese vassals, the Principality of Phuan and Kingdom of Champasak, were annexed into it in 1899 and 1904, respectively.

Theravada Buddhism is the largest and dominant religion in Laos. Theravada Buddhism is central to Lao cultural identity. The national symbol of Laos is the That Luang stupa, a stupa with a pyramidal base capped by the representation of a closed lotus blossom which was built to protect relics of the Buddha. It is practiced by 66% of the population. Almost all ethnic or "lowland" Lao are followers of Theravada Buddhism; however, they constitute only 40-50% of the population. The remainder of the population belongs to at least 48 distinct ethnic minority groups. Most of these ethnic groups are practitioners of Tai folk religions, with beliefs that vary greatly among groups.
Vientiane is the capital and largest city of Laos. Comprising the five urban districts of Vientiane Prefecture, the city is located on the banks of the Mekong, right at the border with Thailand. Vientiane was the administrative capital during French rule and, due to economic growth in recent times, is now the economic center of Laos. The city had a population of 1,001,477 as of the 2023 Census.
The Kingdom of Vientiane was formed in 1707 as a result of the split of the Kingdom of Lan Xang. The kingdom was a Burmese vassal from 1765 to 1779. It then became a Siamese vassal until 1828 when it was annexed by Siam.
