Paksane, Paksan or Muang Pakxan (Lao ປາກຊັນ) (French: Paksane) is a town in Bolikhamsai Province, in western Laos. It is the capital of Paksan District. The Nam Xan River joins the Mekong River at Paksan on the border with Thailand, opposite Bung Kan. Paksan is well connected to the south of Laos by Route 13.
Paksane was founded in the late nineteenth century. The Paksane region had experienced insecurity since the invasion by Annam in 1834, followed by invasions by the Siamese, with the establishment of Siamese sovereignty over Laos in 1836; but especially after 1865, the invasions of "Hos" or "red flags, Chinese gangs from Southern China. These are indeed Hos invasions that began to empty of their populations provinces of Xieng Khouang and Borikhane, but these are the Siamese who complete depopulation by deporting on the right bank of the Mekong much of Phou Eun inhabiting the region to escape the clutches of the invaders.
In 1876, Rama V, King of Siam, ordered the creation of the Muong Borikhane  with the last survivors of the Ho invasion of 1874. Muong Borikhane was placed under the authority of Kha Luang Nong Khai. From 1885, the French who took over the neighboring Vietnam, challenged Siamese sovereignty over Laos, and after Auguste Pavie's mission dating the Mekong to Luang Prabang, the Siamese were forced to leave the left bank of Mekong and evacuate the position they had created at the mouth of the Nam Sane. At that time, Patchoum Muong (or Paxum) was the largest town near the confluence of the Nam Sane, but it is located on the Nam Sane, a half-day's canoe ride up the Mekong.
In the course of the 1890s, missionaries of the Missions étrangères de Paris, attached to the mission of Christianity to a Bangkok-based Keng-Sadok, on the Mekong River, a few miles from the mouth of the Nam Sane. Then the missionaries resumed foot Paksane abandoned by the Siamese and there built a church  . In 1911, Muong Borikhane had about 61 villages with a total population of about 4000 inhabitants. In 1937, when Vientiane province was cut in half, Paksane alone had a population of one thousand people and became the capital of the new province.
