Luang Phabang, (Lao: ຫລວງພະບາງ/ຫຼວງພະບາງ) or Louangphabang (pronounced [lǔaŋ pʰa.bàːŋ]), commonly transliterated into Western languages from the pre-1975 Lao spelling ຫຼວງພຣະບາງ (ຣ = silent r) as Luang Prabang, literally meaning "Royal Buddha Image", is a city in north central Laos, consisting of 58 adjacent villages, of which 33 comprise the UNESCO Town Of Luang Prabang World Heritage Site. It was listed in 1995 for unique and "remarkably" well preserved architectural, religious and cultural heritage, a blend of the rural and urban developments over several centuries, including the French colonial influences during the 19th and 20th centuries.

The centre of the city consists of four main roads and is located on a peninsula at the confluence of the Nam Khan and Mekong River. Luang Prabang is well known for its numerous Buddhist temples and monasteries. Every morning, hundreds of monks from the various monasteries walk through the streets collecting alms. One of the city's major landmarks is Mount Phou Si; a large steep hill which despite the constrained scale of the city, is 150 metres (490 ft) high; a steep staircase leads to Wat Chom Si shrine and an overlook of the city and the rivers.

The city was formerly the capital of a kingdom of the same name. It had also been known by the ancient name of Xieng Thong. It was the royal capital and seat of government of the Kingdom of Laos, until the Pathet Lao takeover in 1975. The city is part of Luang Prabang District of Luang Prabang Province and is the capital and administrative centre of the province. It lies approximately 300 km (186 mi) north of the capital Vientiane. Currently, the population of the city as a whole is roughly 56,000 inhabitants with the UNESCO protected site being inhabited by around 24,000.
